obj does not contain texture links?

malcolm

I'm exporting an obj file from maya but when I open the file it has materials but no textures? Is this a limitation of the file format, if so is there another format which does have texture abilities that can be opened from max or maya? I'm setting up an art test and some of the applicants don't have maya so I need to be able to send them files and they need to be able to send me files back with textures applied in both cases.

Could be an issue with either the exporter or the importer, I never really imported texture-files along with maps earlier, so I think it generally doesn't work or something, I dunno really.

If you look at the modelname.mtl file in a text editor though, it'll look something like this:

# 3ds Max Wavefront OBJ Exporter v0.97b - (c)2007 guruware
# File Created: 17.10.2010 20:07:10

So it deffo does include the maps, but doesn't look like it's actually using em?

As far as I know, OBJ merely stores references to textures that it copies (compresses) in another folder. Collada and FBX are both supposed to be able to embed textures in their files somehow, though in my experience I've found them to be a bit fickle.

Going with .fbx it seems to work.
