.obj

[P1SQ4M]

Ok, I modeled something in max or maya, I want to export it as .obj. I do. Now I want to add it into Irrlicht, but it has multipule textures, and the model is on one node. It did export with a .mtl file, but it didn't drag all the images with it like collada. How can I get all my images to display on my mesh?

I don't think .obj supports several materials per polygon. So it's probably the wrong format to use. I don't know much about available Max3D or Maya exporters as I use Blender myself, but I hacked something together so an artist can add lightmaps to .obj files exported from Maya.

This is basically an .obj format with a few extensions so I can use a second texture as lightmap:

Unfortunately I think that link is down.

Probably a momentary problem. At least works from here.

obj supports multiple textures per object. There are several texture types defined in the material and at least partially supported by the loader. However, if no texture is exported, chances are high that also the texture coords are not exported. This would make the exported mesh pretty useless then, at least non-fixable on the Irrlicht side.

It supports bump-maps as second texture. Just putting 2 textures on one material is not supported.

Wait a sec... do we talk about multiple textures on one polygon or just multiple textures on the whole object? The latter works just fine.

it does support per poly texturing, the trouble is the images need to be relative (and if you using a crappy exporter) the images must be where the mtl file says. Look inside the mtl file in notepad type app, and see where its looking.

irrlicht relies on the exporter doing a proper job of adhering to the standards
