I'm using the latest version of blender (steam)

i dont know why but sometimes when i use high and production quality i get this result

sometimes I always get this result on these settings, sometimes I don't get it.
sometimes the map is just white, but if I choose the quality is low and the medium is always good.

Add options for lightmapping in terms of texel density, resolution options, and various approaches to atlas mapping

https://github.com/mrven/Blender-Texel-Density-Checker

Baking seems to have issues when using GPU with Optix. Probably a Blender bug, but make a soft check/change in case.

Refactor addon for separate moduling:

• Can be easier implemented in Armory3D
• Can easily include other renderers (LuxCoreRender in the future)
• Background (subprocess) and Distributed (network) rendering

Add option to ignore material, even if it's part of an object marked for lightmapping. - Useful in case of emissive surfaces and surfaces with interior parallax geometry, so they don't have to be separated.

Add option for supersampling

This setup results in this error:

Fix error occuring on material restore

After installing the add-on on Blender 2.83 and clicking the "Build Light for selected" button, the process crashes with this message:

File "C:\Users\Thomas\AppData\Roaming\Blender Foundation\Blender\2.83\scripts\addons\HDR_Lightmapper_init_.py", line 449, in execute

It works with 2.82.

Taking a default cube and setting metallic up to one results in a black lightmap.

Fix error for filtering with EXR

I try to install on blender 2.90.1 your addon in the version 0.4.4.3 and 0.4.3.4 but I have this error for both

For information, I already use the version 0.3.2.0 , it's great, thanks

See feature req #2: https://blenderartists.org/t/the-lightmapper-v0-3/1247359/12?u=naxela

When attempting to use Intel's OpenImageDenoise on Linux with Release 0.3 of The Lightmapper, the following error appears in the output log:

Denoiser search: /home/username/Downloads/oidn-1.2.3.x86_64.linux/bin/oidnDenoise.exe
/bin/sh: 1: /home/username/Downloads/oidn-1.2.3.x86_64.linux/bin/oidnDenoise.exe: not found

In Linux, executable files typically don't have any extension and are simply marked as executable. This is the case for OIDN, where the executable is simply named oidnDenoise. Although the user could simply rename the file to oidnDenoise.exe for a temporary workaround, it'd be nice to properly support Linux executables.

Cleaning materials sometimes reverts to an empty material slot. Possibly introduced with 0.3.2.0.

Hello, thank you for the addon !

1. How can i change lightmap resolution ?
2. Can i bake whole scene into one lightmap?
3. How can i use OIDN? i get error -
   
4. Clean lightmap cache not working, i should manually clean graph node for every object
5. Filtering is not working too (
   

Probably denoiser dont understand a border of UV island and take additional space of margin when denoiser work and make the bad result

I have the some error on linux install:

Store material links as properties - So cleaning materials allows for returning to materials with multiple users.

Currently, most is just stashed inside the utility file - Refactoring the addon is necessary in order to allow better development.

its create the same node every time when i click "build light"


after it when i press "build light" again it turns into black

Investigate the possibility of adding external UV mapping interfaces for Blender addons such as UVPackmaster and RizomUV VS

From my understanding, this term should always be pointing at the Material Output node. It does so most of the time correctly. But for some materials it points to a seemingly arbitrary node of the node tree. I modified utility.py starting at line 536 a bit to see what is going on:

for slot in obj.material_slots:
                    nodetree = bpy.data.materials[slot.name].node_tree
                    nodes = nodetree.nodes
                    print(slot.name)
                    #mainNode = nodetree.nodes[0].inputs[0].links[0].from_node
                    ab = nodetree.nodes[0]
                    print(ab)
                    ac = ab.inputs[0]
                    ad = ac.links[0]
                    mainNode = ad.from_node

This is the output, the first couple are for materials where no issues occur and then there is an error:

slot56_slot1_temp
<bpy_struct, ShaderNodeOutputMaterial("Material Output")>
slot60_slot1_temp
<bpy_struct, ShaderNodeOutputMaterial("Material Output")>

Rebuilding the regarding Material -> deleting the nodes and placing them in the exact same way again, fixes the issue for this Material!
Here a .blend where this occurs, the error should simply occur when you press Build Lightmaps.

Refactor and reorganize the caching system with proper cleaning

Hello, thank you for the awesome light-mapping addon!

I was wondering if it would be possible to disable the addon from overriding materials and instead just add an object property with the file-path of the associated lightmap.

Using the gltf addon you can export custom properties like that file path, unfortunately the current way the tool applies lightmaps can mangle gltf materials so that material overwrite needs to be disabled (yes I know that would mean no more previews).

By adding this option you can preserve exported materials and make lightmap associations more clear to import from a hobby rasterizer or small engine without affecting basic gltf materials.

Hopefully this can also be saved as a user preference to avoid accidentally breaking the materials in other files in this workflow.

Thanks!

i use the settings

Add some video tutorials about how to get started with lightmapping surfaces and lighting conditions.

In the options for the individual objects, there are UV option. You can choose Smart, Lightmap, or Copy. Smart and Lightmap unfortunately produce the same broken result, where some faces are squeezed into zero-width/height faces on the UV map. Copy works fine. Win10 b2.81a

Investigate ways to blend seams together, or make them less apparent

Your toolset looks awesome. Would it be possible running it headless mode?
Something like this:
blender --background --python run_The_Lightmapper.py

Essentially I would like the script to import a gltf/obj file then do all of the magic that your tools do (unwrapping, baking etc) and then export a new gltf/obj file. I'll probably consume the output in babylon.js

Find a way to begin map atlasing, preferably with atlas grouping based on object size and resolution

Right now the console information is messy

Hello,

first of all great add-on ! I think if this is will be pushed a bit it will drastically improve the hole process of baking !

I was experimenting with your newest version (added some code to link the baked lightmap node to a gltfSettings node to export it to glb and use it in three js) and figured that the denoising doesn't work anymore cause the denoised image can't be found. I tried to use the pipe from an older version but I don't really understand whats going on here.

Old version just gives a black image, new version gives this error

I couldn't find the file in the Lightmaps folder so I guess it wasn't saved.

Could you help me ?

Atlas postpacking mode doesn't keep existing UV layers if they're present.

Hello,

I really like your addon and I would love to bake the textures with AWS to accelerate the process. Is it possible to use the command line to open the .blend file, adjust some settings like quality, filtering, .., bake the lightmap and save it as hdr?

Thanks for you me advise :)

Hello, I recently installed this addon that is very useful to me and I have detected this error, which does not allow me to use the denoise neither from nvidia or from optix.

Sorry for my poor english.

Find some way to bake directional information (dominant light) to texture. Cycles and OSL doesn't work. Possibly as an external RTX module.

Add filtering as stacked list, allowing multiple filters to be used in terms of postprocessing.

Additional filters to be implemented:

• Brightness
• Saturation
• Contrast

More material checks for unsupported material setups, such as materials prepared for Blender internal render (from 2.79)

If an object is to designated to be lightmapped, but hidden - Error will occur: No valid selected objects

When baking, turn off all baked materials while baking on a selection based routine - Make a list of baked materials, re-apply after baking.

Baking while other objects has baked materials will provide faulty results in strong light conditions.

Blender 2.91 provides a few breaking API changes that needs to be sorted out. These currently provide stopping bugs

It would be nice if the addon could export to Open EXR as well. Many texture processing pipelines (such as ones using AMD's Compressionator) don't support .hdr files.

Getting AO baking error when working with multiple objects.

Todo: Fix

Make some more context poll check and warn when the context is wrong

when i was install the addon give me this problem.

This seems to happen when a change is made to a material on a light mapped object. Not sure what change was made, but I think it was a name change. Once this error showed up, light baking broke for one of the materials in question. This error only seems to appear when Don't apply materials is checked.

Additionally, completely deleting all material data (orphan data included) and remaking them all from scratch seemed to not fix the issue. I suspect the only option here is to recreate the file.

Edit: For reference, I am using Blender 2.9

Hi, i just recently found this addon, and really help, but my main problem is i can't get the OIDN denoiser working, how to use the OIDN? Where do i put OIDN Path?
I'm using windows 10, blender 2.83

Thank you

Fix error where lighmaps aren't encoded during background baking (in UI), denoising works, filtering works, but error related to encoding with GPU, although should only be the case for LogLuv
