Hey Pawel
if you can't get an mtl file for your obj, then you can always try
overriding your materials with a single material for the entire obj file.
the material property on the Obj parse can be set before it is used on an
obj file. With this in place, all materials encountered in the file use this
material definition. So you can set it to BitmapMaterial, ColorMaterial...
whataver you want
Once an obj file is loaded, the materialLibrary property on the parser or
the returned away3d object hold the names of all materials defined in the
obj format. If you want, you can set the material of each individually by
doing something like:
myObject.materialLibrary.getMaterial("myMaterialName").material = myNew
Material
This approach will preserve multiple materials in an obj loaded file
hth!
