Hi Geolux,

You might want to give us a link towards a file that can't be correctly loaded.
In my experience, i've had troubles to load some files on Windows if there was something weird in the path to tifle (éèà, a space, ...).
If you haven't, you can try to put your file at C:\ and rename it test.ply

Yes the support for textures for PLY files is not something that was specified from the start. Therefore textures are described in the 'comments' section of the file! And the file is always external (the 'comments' section only contains its name).

In the zip file you sent, there's no image file next to the PLY files... If you look at the beginning of the 'mesh' file, you'll see that it needs the 'Altare_ZephyrMesh.png' file.

Ok I understand now. It's because the texture coordinates are not saved as a 2D array (like "texture_uv" - as usual) but as 2 separate arrays (texture_u and texture_v). I really wonder what the people developing these software are thinking about ...

I'll see if it's possible to handle such organization, but anyway it will take time!
