bitmap material on OBJ ( jit.gl.model ) export from blender software

January 4, 2012 | 12:57 pm

hi guys!

searched all over the forum and I can’t find the method for proper exporting a WAVEFRONT OBJ from blender – so that jit.gl.model can import it properly with bitmap materials.

I have checked for the apple.obj example – when I replace the filename (skin.tif) in the material file apple.mtl with my own bitmap it recognises it OK.

But HOW TO EXPORT OBJ FROM BLENDER 2.61 in order for max 5 to read it nicely with bitmaps properly recognised?

Any ideas?

Thanks!!!

Dariusz

P.S. here’s what I have in my OBJ and MTL files:

CUBETEST.OBJ

dear robert,

thank you for your reply.

the problem is that there’s no picture (material) visible when I open my model in jit.gl.model in jitter.

I get the object but without the texture.

please find another example of the same problem in the attachment – I also included the setting screenshots of what i have in blender upon export.

I can’t figure out what am I doing wrong???

hi Dariusz– you need to uv map your image in blender in the UV image editor. In your first screenshot the mapping has to be coordinates set to UV. Attached are screenshots– my diffuse influence is set to alpha for transparency.
