The view3dscene command-line options to --write-encoding=xml appear to fail with an Exception "EAccessViolation": Access violation when attempting to convert a GLTF object to X3D. The same process performed through the GUI menus with the same model works without issue.

To replicate this issue, pick one of the GLTF examples in https://castle-engine.io/demo_models.php and upload with defaults to https://castle-engine.io/convert.php. The service returns error code zero. Closer inspection on a local build reveals that view3Dscene produces "Exception "EAccessViolation": Access violation" which may reflect the same issue causing failures in https://castle-engine.io/convert.php.

I've been looking for something to easily convert Collada (.dae) models from Sketchup into something commonly read by CAD programs preferably .step. view3dscene loads .dae files wonderfully, but the .x3d format is troublesome. Is there any chance of adding support for .step?

thanks for the best VRML-viewer for Linux;
is there a way for VRML2- files to shade IndexedFaceSets from both sides -

(no rush, I can view it with three.js and babylon.js fairly well.

(looking for an integration with X3D).

Thanks!

I am using version 3.18.0. If I am loading a obj file which comes with an mtl and jpg as texture, I get the following message.

The obj file has a size of 50MB, the texture file is 7MByte. Other tools manage to show the 3D model with texture information. Is there any way of getting more information about the problem?

Hi Michalis,

based on your 'animate_tex_coord.x3dv'-example, I tried to animate the background image:

but ImageBackground seems to ignore everything, despite the fact, that it does not ignore vertical or horizontal scaling via texCoords!

You wrote, that 'ImageBackground rendering is a little special' -- is that the cause or am I missing something?

BTW.:

• It would be cool, if the user could set the default screen geometry in the 'Preferences'-menu of View3DScene (so that it ends up in the 'view3dscene.conf' file) and View3DScene from that point on would always start with the prefered screen size -- the example above for instance only works acceptable for quadratic ImageBackgrounds.

• I think it would have been more 'elegant' to use a spline based interpolation for the computation of the texture coordinates, but SplinePositionInterpolator2D is for SFVec2f-output only. I tried to compensate the linear interpolation of CoordinateInterpolator2D by using 36 x 4 different s,t positions on the circular circumfence of the quad ...

• Some of your animation examples on github (like animate_tex_coord.x3dv) were appearantly shifted to a deeper nested directory, so that all the texture/movie_texture references do not work anymore. In demo_models-3.9.0.zip everything seems to be alright.

• I still couldn't find the reason, why InstantPlayer doesn't run on my system -- does it need
  Win10 Professional, a pure Intel processor as stated here (I've got a AMD E1-2500 mobility APU) or some exotic additional libraries/.dlls? -- I have trieded dozens of things, like installing as administrator, installing the old 32-bit versions of InstantReality, copying the mfc/vcrt120.dlls into InstantRealitiy's bin-directory, using sfc.exe and dism.exe to check for integrity faults in Win10's component store (WinSxS) and repair them etc. -- nothing worked: still error 0xC000007B -- and according to the internet, I am the only one among 7 billion inhabitants of this planet, who is experiencing this problem :(

But never mind -- if you please could:

• add a geometry option to 'Preferences'-menu and 'view3dscene.conf'-file and
• fix the ImageBackground texCoords animation issue or
• tell me where I am mistaken,

I would be glad.

Please keep in mind, that I can not test my X3D files with InstantPlayer [see above] to see, if they work there -- so don't be angry at me, if I ask for something, that does not even work with InstantPlayer.

With best regards,

Elmar

Converting the Lucy model from
http://www.seamless3d.com/browser_test/lucy_test0.x3dvz
to X3D XML encoding with 3.18 results in this file:
https://raw.githubusercontent.com/andreasplesch/x3dom/HAnim_work/test/functional/HAnim/Lucy_test0.x3d

It seems during conversion the rotations somehow get inverted.

Here is X3D XML encoded scene:
https://raw.githubusercontent.com/andreasplesch/x3dom/HAnim_work/test/functional/HAnim/Lucy_test0b.x3d
converted by
http://doc.instantreality.org/tools/x3d_encoding_converter/
It has correct rotations.

As I heard view3dscene can convert files to X3D/VRML, the only main color formats supported by Shapeways, I tried opening an OBJ file from Tinkercad, which stores the model's solid colors in its MTL file. When opening a file from Tinkercad, this error appears:

Error while loading scene from [file path]: "0.0" is a invalid integer.

The MTL file it tries to read contains this:

Reproducing

To reproduce this error, just extract the model files from this ZIP file then attempt to open the OBJ file in view3dscene. That error will appear then it will cancel loading the model.

New Juice Cylinder (1).zip

This test scene:

http://x3dom-sequencer-interval-test.glitch.me/IntegerKeyTest.x3d

has sequence keys=0,0.5,1 and keyValues=0,1,2

Most x3d browsers show this result:
key < 0: value is 0
key = 0: value is 0
key = 0.25: value is 0
key = 0.5: value is 1
key = 1: value is 2
key > 1: value is 2

However, view3dscene shows this result:
key < 0: value is 0
key = 0: value is 0
key = 0.25: value is 0
key = 0.5: value is 0
key = 1: value is 2
key > 1: value is 2

For key = 0.5 the second interval [0.5,1) should be selected giving a keyValue of 1 since 0.5 is part of this interval. 0.5 is excluded from the first interval [0,0.5).

It could be a floating point comparison issue.
This is probably more a castle-engine issue.

Hi Michalis,

while testing some of my X3D files I came across a problem with the Viewpoint node:

centerOfRotation seems to get altered by some internal View3DScene mechanism under certain conditions (even when there is no explicit Viewpoint given in the X3D file)!

Try to rotate the cube and you'll see what I mean ...

My best guess: some automatic scene centering mechanism tries to compensate the movement of the Text node (which makes the scene somewhat 'a-symetrical').

I can correct this behavior partially by adding a big (size="40 40 40") fully transparent cube to the scene, but that's not really a good solution.

BTW.: When I try to print out the Viewpoint settings with "Clipboard -> Print Current Camera...", I only get position and orientation but not centerOfRotation and fieldOfView, which are essential to re-create the exact view!

So please:

• Add centerOfRotation and fieldOfView to the "Print Current Camera..." menu and
• Tell me how to get around the centerOfRotation problem.

With best regards,

Elmar

P.S.: here is the the test file: view3dscene_issue_20.zip

MouseWheel works on Walk navigation only after you select Fly (where Wheel works) and then select Walk again.

Can be reproduced by opening demo-models/navigation/type_nav.wrl

Still I think walking using MouseWheel is very strange. I still feel it would be best to use it to Rotate Up/Down instead for all of us who navigate using mouse exclusively.

Regardless on resolving the MouseWheel for walking or tilting, it is not possible to rotate the look even in view3dscene. It is very frustrating. What about setting keyU / keyJ (or any standard key, PageUp perhaps?) as defaults for Input_UpRotate / Input_DownRotate in CastleCameras for all CGE apps?

In README.md there is mention on converting into VRML:

You can also convert all models to X3D or VRML.

But if open *.x3d file in view3dscene there are NO .wrl format to choose in "File > Save as VRML/X3D (classic encoding)..." — only *.x3dv is available to choose.

Also there are NO any CLI-arguments in tovrmlx3d to convert input files into VRML format (only X3D):

• https://castle-engine.io/view3dscene.php#section_converting

view3dscene reports an excess field, description, in at least 2 nodes. This is due to a number of description fields being added to X3D4. Two I found serendipitously are in nodes ImageTexture and HAnimDisplacer. As documented in emails from myself and Doug Sanden, the X3D Tooltips report that these are new to X3D4 (yellow background). AFAIK, this should not affect any functionality that i know of, except accessibility.

https://castle-engine.io/x3d_implementation_shape.php#section_supported_nodes

says that TwoSidedMaterial is somewhat supported.

But

(https://x3dgraphics.com/examples/X3dForWebAuthors/Chapter05AppearanceMaterialTextures/TwoSidedMaterialIndex.html)

renders white in view3dscene 3.18

Hi Michalis,

I have been trying to establish a kind of static background image for one of my models.

In X3DOM there is the <Background backUrl='test.jpg'></Background>-trick (non-standard of course).

In Instant Reality Player there is PolygonBackground and ImageBackground (both non-standard too),

and then there are at least two ways to do it in standard-X3D:
<ScreenGroup> with <Billboard> and <LayerSet> with <Layer>

but all my attempts to make these two work in View3DScene failed!

The most interesting one for me is the LayerSet/Layer-approach, because this works in x_ite 4.5.11:

Is there any other standard-X3D possibility to set a static background I have overlooked?

Please help!

Either give me a hint, how to do it, or fix the LayerSet/Layer-nodes, because they are very usefull for a lot of things, like HUDs, Copyrights, Backdrops etc.

With best regards,

Elmar

P.S.: here are my test files: view3dscene_issue_18.zip

In X3D scenes without an explicit viewpoint node, the initial camera position is at 0,0,0. However, the default X3D viewpoint position is at 0,0,10.
It is easy to use the menu to navigate to the default X3D viewpoint but it took me a while to realize that there was not any problem with a scene itself, just the ciew3dscene initial camera position.
Here is an example:

I'm hoping you can look into my glTF to X3D conversion request for your software? I think the glTF may have an embedded .bin file. I don't know if that's convertible or not. I don't even know what a .bin file is. It would seem that the glTF file including (or not including) the scene.bin would convert though. I guess X3DOM has a way to read .bin's. Here is the glTF link in question: http://www.kshell.com/pages/gltfassets/toomuchcoffee/scene.gltf There may be a creative commons license. Go to http://www.kshell.com/pages/gltfassets/toomuchcoffee/ for License and original model. I would love to see a snapshot of the scene in view3dscene on Linux! If you like, I will file an issue in your github repository. I assume I file it against the view3dscene repository?

Wasn't sure whether to put this in CGE or here but found it here so...

Kenney stuff is all CC0 so perfect for CGE...

Go grab the latest Kenney pack - https://www.kenney.nl/assets/city-kit-suburban

Extract it and navigate to Models/GLTF format

Try opening one of the *.glb models - Access Violation under Ubunto 20 + Windows 10

Works in Blender...

The OBJ is fine

Hi everyone,

I'm doing a comparision between different X3D players for my master thesis with Dr. Brutzman at the Naval Postgraduate School. I created a scene showing the Olympic Rings using extrusions. Your player gave me the hint, that something with my extrusion was wrong. I fixed the model and there are no more errors in the console. Octaga and Instant Reality are displaying it perfectly.
Could you help me to find out, whether it is an issue with my model or with the player?

You can find the model on gitlab.nps.edu:

https://gitlab.nps.edu/Savage/mv3204x3dforwebauthors/-/blob/master/assignments/DirectedStudy/Tobias/Scenes/OlympicRings.x3d

Thank you very much for your help.

I did some tests on localization with the default font. The German characters "ß,ä,ü,ö" are missing.

Console output:

3 warnings:

Font is missing glyph for character ß (Unicode number 223)
Font is missing glyph for character ä (Unicode number 228)
No further warnings about missing glyphs will be reported for this font (to avoid slowing down the application by flooding the log with warnings)

When running view3dscene on macOS (I have macOS 13.1 Ventura), I cannot click on any toolbar button. When I run menu command Help - About, I cannot even click the Close button, but I can close the About box using Enter.

Tested both on the stable release (v4.2.0) and daily snapshot (v4.3.0).

It seems the scene steals all mouse clicks, as I can drag-rotate the scene when I click on the toolbar buttons.

Hi, Michalis!

My name is Elmar Knittel and I live in Germany.

I've just tested the new version 3.18.0 of your fantastic
program "view3dscene" (best VRML-viewer ever) on Windows.

    view3dscene_3.18.0-win64-x86_64 on
    Windows 10.0.17763.134-x64-Home

The new shader-pipeline has some issues running on my
AMD E1-2500 APU (AMD Radeon HD 8200 / R3 Series, see below),
that weren't there with the fixed pipeline in ver 3.17.0
and which vanish if I use "--debug-enable-fixed-function"
or if I use additional VRML/X3D nodes (see examples).

===================================================================

A simple VRML 1.0 file like:

    #VRML V1.0 ascii
    Separator {
     Texture2 { image 1 1 3 -1 }
     Coordinate3 { point [ 0 1 0, -1 -1 0, 1 -1 0 ] }
     IndexedFaceSet { coordIndex [ 0,1,2,-1 ] }
    }

dosn't work, but adding:

    "MaterialBinding { value PER_PART }"

makes view3dscene 3.18.0 display the triangle correctly,
even without "--debug-enable-fixed-function" set:

    #VRML V1.0 ascii
    Separator {
     Texture2 { image 1 1 3 -1 }
     MaterialBinding { value PER_PART } # added line!
     Coordinate3 { point [ 0 1 0, -1 -1 0, 1 -1 0 ] }
     IndexedFaceSet { coordIndex [ 0,1,2,-1 ] }
    }

===================================================================

Almost the same goes for VRML97/X3D:

    #VRML V2.0 utf8
    Shape {
     appearance Appearance { material Material {}
      texture PixelTexture { image 1 1 3 -1 }
     }
     geometry IndexedFaceSet { coordIndex [ 0,1,2,-1 ]
      coord Coordinate { point [ 0 1 0, -1 -1 0, 1 -1 0 ] }
     }
    }

doesn't work, but adding:

    "color Color { color .8 .8 .8 } colorIndex [ 0,0,0 ]"

does the job:

    #VRML V2.0 utf8
    Shape {
     appearance Appearance { material Material {}
      texture PixelTexture { image 1 1 3 -1 }
     }
     geometry IndexedFaceSet { coordIndex [ 0,1,2,-1 ]
      coord Coordinate { point [ 0 1 0, -1 -1 0, 1 -1 0 ] }
      color Color { color .8 .8 .8 } colorIndex [ 0,0,0 ] # added line!
     }
    }

===================================================================

A second (minor) issue is that anti-aliasing is disabled when the option:

    "Screenshot to Image (Transparent Background) ..." or
    "Screenshot to Video / Multiple Images (Transparent Background) ..."

from the "Display" menu is chosen (all tested versions).

The resulting snapshots look pretty "jagged" at the object edges.

===================================================================

A third (minor) issue is that view3dscene (in all versions) doesn't
gracefully handle situations when the "view3dscene.conf" file is
read-only to guarantee the same settings for all VRML/X3D files.

    Exception 'EFCreateError'
    Unable to create file
    'C:\User\XXXX\AppData\Local\view3dscene\view3dscene.conf'

    An unhandled exception occurred at $000000010003293B:
    EFCreateError: Unable to create file
    'C:\User\XXXX\AppData\Local\view3dscene\view3dscene.conf'
    $000000010003293B
    $000 ... etc.

===================================================================

A fourth issue might be (I'm not shure) that "freetype-6.dll" is missing
in the downloadable ZIP-file from:

    "https://michalis.ii.uni.wroc.pl/view3dscene-snapshots/".

===================================================================

And at last a Cristmas wish:

    *Please* implement ECMA-Script for view3dscene,
    to make it more standard conformant and because
    there are thousands of VRML/X3D files using it.

With best regards, Elmar.

Can not be compiled from source.

When trying step 7 of https://castle-engine.io/compiling_from_source.php

Looks trivial, but who knows.

Also, probably unrelated, when i click on the striken-out files and then say "no" to new file creation prompt - the IDE gives me a totalyl undecipherable AV window.

Also, why compilation from sources manual contain those "copy exe file" instructions? Won't it be better to setuup the project just to output release exe there? Maybe i am saying something stupid, as i am coming from Delphi background, but that is what i'd be doing in Delphi as default option.

In x3d encoding, leading white space in front of the castlescript: identifier in the value for the url field of a script node provokes a parsing error.

Perhaps this is intended but probably not. Could provide an example by converting the ballgame example to x3d and adding a space.

Hi Michalis,

I have found a Utah teapot that uses Bezier-patches in Renderman .RIB format here and converted it with the help of Ayam 1.26 and WhiteDune 1.212 and a lot of manual simplification to X3D/X3DOM!

Rendered with X3DOM-1.8.1-dev snapshot it looks like this:

but rendered with View3dscene 3.18.0-20190817 (zoomed to the max) it looks like this:

Am I missing something?

Because this renders O.K.! -- look here:

I don't get it! Why does the spaceship (composed of 6 order-4-NurbsPatchSurface-nodes) work and the teapot (composed of 64 order-4-NurbsPatchSurface-nodes) doesn't?

May-be because I omitted the weight-property?

It would be: weight='1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1' for all NurbsPatchSurface-Nodes and seems to be omittable, because according to the spec, the default weight of 1.0 is assumed for each control point.

Please help me!

With best regards,

Elmar

P.S.: I attach the used files: view3dscene_issue_17.zip

Script nodes can have inlined code using a special ecmascript protocol. Here is an example:

http://www.web3d.org/x3d/content/examples/ConformanceNist/Miscellaneous/Script/ScriptNodeEventOutControl_EcmaScriptIndex.html

The x3d:
http://www.web3d.org/x3d/content/examples/ConformanceNist/Miscellaneous/Script/ScriptNodeEventOutControl_EcmaScript.x3d

There is an error that no supported protocol is found and script is ignored,

This is especially useful for protos in order to keep everything in a single file.

I have a VRML 2.0 file created by a third party that I am trying to convert to X3D. When using tovrmlx3d it prints a load of warnings such as:
tovrmlx3d: Warning: VRML/X3D: Cycles in VRML/X3D graph: USE clause inside node "Caution_1_d31" refers to the same node
but then seems to just hang and never completes. I have tried v4.0.0 and v4.1.0.

Can anyone offer any guidance?

seems to be edge-case where lighting calculation going awry.

happens when geometry concave && scaled very small && moving.

OK - maybe I'm expecting too much :)

I just threw together a test for the new and really useful TextureNode.LoadFromImage(TextureImage, TakeOwnership, ImageURL);

I noticed I can set the URL to wherever I want so I set it to the real URL (even though testing with a local copy) and used the new SaveNode method to write out the x3dv

Loading the x3dv back into view3dscene raises the following warnings...

The 'back.jpg' I can actually correct for now (static, local) but the internetified image (its real) needs TDownload enabling

2 warnings:

Hi Michalis,

it's me, Elmar (again).

I recently stumbled over a regression issue in the newest CGE/View3DScene:

view3dscene-3.18.0-win64-x86_64.zip - 2020-04-01 08:27

Since the introduction of PhysicalMaterial/UnlitMaterial the old (v3.x-style)
Material node behaves differently regarding emissiveColor and its relation to
diffuseColor.

#X3D V3.3 utf8
PROFILE Full
Shape {
 appearance Appearance {
  material Material { diffuseColor 0 0 0 emissiveColor 1 0 0 }
 }
 geometry Box {}
}

used to produce a pure emissive red material -- but now its pitch black and
by this breaks backward compatibility to over 1500 of my VRML/X3D-files.

Increasing the amount of diffuseColor just a tiny bit, like so:

#X3D V3.3 utf8
PROFILE Full
Shape {
 appearance Appearance {
  material Material { diffuseColor 1e-6 1e-6 1e-6 emissiveColor 1 0 0 }
 }
 geometry Box {}
}

brings back the original behavior that worked for many years...

You probably understand, that I would rather not change all my existing files
to comply with the new behavior - though I intend to use UnlitMaterial in
future files as soon as X3D v4.0 is official.

Meanwhile I use:

#X3D V3.3 utf8
PROFILE Full
Shape {
 appearance Appearance {
  texture PixelTexture { image 1 1 3 0xFF0000 }
 }
 geometry Box {}
}

which is shorter and an acceptable workaround for the time beeing...

I hope it is possible to fix this, without tempering with the new PBR features!

With best regards,

Elmar

P.S.:

The new glTF/glb feature (skinned animation) is really cool - though it does
not work with all files I've tested so far, e.g. "Bee.glb" that came with
Microsoft's 3D-Viewer v5.1811.27012.0: it takes very long to load (normal),
does not display any of the textures (just dull grey) and the animations are
extremly slowly - even when I throttle up animation speed to maximum!

PasGLTFViewer (https://github.com/BeRo1985/pasgltf) has no issues with "Bee.glb"!

You can download "Bee.glb" (20MB) from:

https://github.com/leation/mydata/raw/master/Bee.glb

Hi Michalis,

its me, Elmar.

I discovered that recent view3dscene win64 compiles (view3dscene-3.19.0-win64-x86_64.zip - 24-Jan-2021 19:59 - 6573059) show an GLSL shader compile error in the logfile (see attached/zipped view3dscene.log) for all built-in effect shaders,

Warning: GLSL: Error when initializing GLSL shader for ScreenEffect[Visualize Depth]: Fragment shader not compiled:
Fragment shader failed to compile with the following errors:
ERROR: 0:247: error(#132) Syntax error: ")" parse error
ERROR: error(#273) 1 compilation errors.  No code generated

that didn't occur with older versions of view3dscene (like: view3dscene_3.19.0-win64-x86_64 - 23-Oct-2020 08:00), so that
the built-in effect shaders can't be activated from the menu (e.g.: View->Screen Effects->Visualize Depth) anymore, no matter
if used with or without --debug-enable-fixed-function

Effect shaders within loaded x3d/x3dv-files (example included in zip file) seem to work, as far I can tell.

Please help...

Yours,
Elmar

Hi Michalis,

it's again me, Elmar!

I've tested the latest view3dscene-4.3.0-win64-x86_64 from 14-Dec-2022 02:55.

When I scale in and out my test-scene (see attachment), the scaling gets "stuck" at some point and rotating disjoints the red cube from its center position.

The latter problem vanishes if I out-comment "ROUTE PS.position_changed TO COPYRIGHT.set_translation".

These problems do not occur with version 4.2.0 of view3dscene ...

Please help!

Regards,

Elmar

When I use an Anchor to switch from one VRML (or X3D) file to another, View3DScene reports an "access violation", although you can continue to browse the new file. My experimentation finds that this occurs only if there is a script in the 2nd file of type "castlescript". Because if I overtype the script type with "javascript", although this would keep the script from working, it does get rid of the access violation.

To help you recreate the bug, I have attached two small vrml files redcube.txt and bluecube.txt. Change the extension of both to .wrl then open redcube.wrl in View3DScene. Click on the red cube, which will transfer you to bluecube.wrl. A do-nothing castlescript was included in bluecube.wrl, which causes the access violation. Try replacing "castlescript:" with "javascript:", and see if this eliminates this fault.

bluecube.txt
redcube.txt

view3dscene uses standard, but not always installed external libraries. For example, on debian the libgtkglext1 package is required:

https://packages.debian.org/search?keywords=libgtkglext1

It would be great if there would be a list somewhere which libraries are needed. Perhaps fpc has such a list somewhere already ?

According to the spec, when a shape is lit and there's an RGB texture, I_DRGB should not be used.

Some further discussion at create3000/x_ite#50, including a note that ignoring the spec does give more flexibility, but the concerns about feasibility of detecting RGB vs intensity textures shouldn't apply in a non-web context (although I don't know what other considerations may be at play).

This affects ability to view spec compliant files, although switching a default now could adversely affect compatibility with assets intended for use with Castle Engine.

Hi i was using view3dscene. since i updated to mac os catalina i'm not able to run the app anymore. does it exists a 64 bit release for mac os?

is there any other free software able to view wrl files on mac os?

When I put a pointlight into the scene at 0 0 45 and my viewpoint is at 0 0 45, the scene shoud be well lit, but I have to turn the rings 180° around y-axis to see the light.

view3dscene-3.18.0-win64-x86_64.zip | 2020-03-10 06:09 | 4.1M | Latest Windows version (64-bit)

and got following complaint by view3dscene when I use an 'Effect' shader:

VRML/X3D: Plug name "texture_apply" not declared (in shader type "Fragment")

although this file worked perfectly with an older view3dscene snapshot from 2020-02-20!

it should look like this:

It does work when I use a complete 'ComposedShader' --- am I missing something?

I'll attach the test files (both: Effect shader and ComposedShader version) for you to test.

Please help!

With best regards,

Elmar

Hi Michalis,

it's me again, Elmar...

I just found a problem when loading a simple Wavefront .obj/.mtl file that I exported from MeshLab 2021.07 (https://github.com/cnr-isti-vclab/meshlab/releases):

I attach the .obj+.mtl files and the view3dscene.log: view3dscene_issue_40.zip

Hi Michalis,

it's me again, Elmar...

I just found some problems with View3DScene.exe from 12-Jun-2022 19:30: https://jenkins.castle-engine.io/public/builds/view3dscene/view3dscene-4.1.0-win64-x86_64.zip

1. TextureProperties {} does not set the defaults (like: magnificationFilter to "FASTEST") anymore.
   See: https://www.web3d.org/documents/specifications/19775-1/V3.3/Part01/components/texturing.html#TextureProperties
   This forces me to manually alter hundreds of files that are carefully formatted to keep a 80 characters line limit...

2. PLUG_texture_apply is now deprecated.
   View3DScene gives the following error message:

Using PLUG_texture_apply is deprecated. Upgrade to 1. PLUG_main_texture_apply (to do something after main texture application; but remember that it happens before lighting application in case of Phong shading), 2. or PLUG_fragment_modify (to do final fragment color adjustment)

You had fixed this in 2020:

#24
michaliskambi commented on 11 Mar 2020
I pushed a simple fix to enable PLUG name texture_apply for backward compatibility.

This forces me to manually alter hundreds of files that are carefully formatted to keep a 80 characters line limit...

3. Export to JP2 (JEPEG2000) files does not work at all.
   View3DScene gives the following error message (that cannot be send to clipboard):

Unable to save screen: Cannot save image to file format jp2 using Vampyre Imaging

Please help...

with best regards,

Elmar
