exporting into .obj and .mtl problem with textures

exporting into .obj and .mtl problem with textures

(OP)
Hi all, fairly new at 3D modeling/programming.

I've created a very basic scene, two shapesin fact. Each has it's own texture. Saving and loading the fxw file is fine, no problems in displaying the texture. However, when I export the scene to wavefront .obj format, the .mtl file it produces looks like this:

# File produced by

newmtl dad_Roof
Ns 4
d 1
illum 2

Ka 0.200000 0.200000 0.200000

Please note the missing texture in the newmtl dad_Roof. However, loading the fxw file will correct display the Roof and Walls with the right texture, hence its something to do with exporting.

What I then intended to do was import this file into a Model Loader in Java3D. This is when I nocticed that the whole scene (all two objects) was only one texture (the texture being used on the walls).

I decided to then "import" the same file I exported out from Flux Studio and see what Flux Studio made of this odd .mtl file. When I did this the roof object was a mat red and no longer displayed it's texture unlike had I loaded it from the fxw file.

Help! How can I export two textures in a paired .obj and .mtl file. What am I doing wrong.

Thanks very much.
