mviewer's Introduction

MView File Viewer

This project consists of 2 scripts. extract_mview to extract files inside the mview archive and extract_model to convert the .dat files to .obj.

Also includes a Noesis plugin. (see below)

Example

File downloaded from ArtStation.

Viewer

You can download Noesis from here. Copy and paste the plugin to noesis/plugins/python/fmt_artstation_mview.py then just open the .mview files with Noesis.

Notes

To download an .mview file:

Open url with 3D viewer in browser. (do not click play yet)
Open Developer Tools and go to Network tab.
Click the play button on the 3D viewer.
Type or search for mview on the Developer Tools' Network tab.
Right click on the file and select open in new tab. (will start download)

[FIXED] ~~[BUG] There is currently no support for huge files that uses uint32 indices. Pull requests are welcome.~~

mviewer's Issues

Where does the generated obj get stored?

Maybe a silly question, but where's the final obj stored? I noticed I have an obj for each .dat file. I'm going to try and load each of them but it would be nice to have that included in the README.md

TypeError: unsupported operand type(s) for <<: 'str' and 'int'

Getting a failure running the batch file/extract_mview.py. If I try Noesis plugin, only half the model renders correctly, the rest is jumbled vertices. Python 3.6.1 on Windows 10.

Console output:
('thumbnail.jpg', 'image/jpeg')
Traceback (most recent call last):

Noesis bone renaming issue

Noesis sometimes gives this error:
WARNING: Duplicate bone names, overriding.
which causes Noesis to rename all the bones, which breaks all the animations. Please add an option to force Noesis to not rename bones!

Noesis export file does not have 'mtl'?

only exports jpeg

I found a problem when exporting Artstation's model！

      When I import a complex model from Artstation, if the number of textures of this model must be larger than 6, then the textures and models will be lost in the software.
     When I saw your code, I found that the maximum number of textures you set was 6.
     Please tell me how to change it！

Windows Version error

running the windows batch, yields errors on line

it has something to do with scene.json as i see it

Textures are messed up.

When I extract everything, the textures are messed up

it should look like

Instructions for non-programmers please?

This looks brilliant, but after downloading and installing Python I'm stumped.
running the script (.py) does nothing that I can see.
Could someone please write simple instructions for us non-programmers/developers?
Thanks!

Found solution for Gamebryo NIF 20.6.0.0

Version 4.425 of Noesis is unable to open some NIF files with version 20.6.0.0, raising exceptions like "Unreasonable texture list size" and "Unreasonable shader map list size".
After some experiments, I was able to partially fix this issue by preventing Noesis from attempting loading textures.
It's a first step, but also adding textures is important... Unfortunately I don't know anything about textures and NIF files, I was just lucky with this hack.

I attach the modified fmt_gamebryo_nif.py file

Noesis Python Error

When open a downloaded mview file, Noesis Python Error. ToT

Traceback (most recent call last):
File
".......\noesis\plugins\phython\fmt_artstation_mview.py", line 33, in loadModel
diffuse = loadTex(files, fdiffuse)
File
".......\noesis\plugins\phython\fmt_artstation_mview.py", line 217, in loadTex
tex.name = fname
AttributeError: 'NoneType' object has no attribute 'name'

the model is flipped and textures mismatched

is there a fix for this?

it turns out the uv maps are simply displayed the wrong way up, however the alpha maps don't seem to carry over properly

Error in code

No video guide for installing Mviewer and using it

There isn't a video guide for installing this program, opening a file, and unpacking it

Not relevant?

Ripper no longer relevant?

Model extraction error

https://www.artstation.com/artwork/Pm62d4
This address.
Model extraction point collapse
please help

'extract.bat' and 'Noesis' export files are not the same

extract.bat:

sometimes missing 'obj' file

Noesis:

missing 'mtl' file

Plugin exports incorrect texture filenames

This seems to be inconsistent behaviour.

When exporting to obj/fbx, the texture filenames are sometimes "scene_000.png", "scene_001.png" etc.

Try exporting and reopening within Noesis - sometimes the textures are preserved ("mat1_c", "mat1_r", "mat1_n" etc.) and all the textures are found/resolved on reopening. (test_file13-19 export properly).
