help: uv/textures/export

[kaolin]

I'm trying to export a model for Unity. I've tried Collada and Obj and 3ds, but I've had no luck getting the textures to actually stick. (I've also tried to load them in Blender, with same failure—no textures).

I've tried Wings3d 2.0.2 and 1.5.4 (the models were built in 1.5.4).

I followed the pagoda productions tutorial ~ http://www.pagodaproductions.com/tiki/Wi...pping.html

Everything looks fine in Wings3d.

I've tried with "make internal" and "make external" on the textures.

Any thoughts on something obvious I might be missing? Or how I might start figuring out what's wrong? Is there a limit to the number of materials/textures I can use? Could I have screwed up the UV/attachment by editing the models? Partially lost the attachment to the materials by renaming something wrong? (the materials are definitely attached to the faces, the faces are definitely showing the textures, in the wings3d editor...). Is there a second step I should be doing to copy textures around? Should I just get some sleep and everything will be clear in the morning?
