help: uv/textures/export

[kaolin]

Thanks!

Should I expect Wings3D to export the textures into the same directory as the obj + mtl, or do I need to match those up manually (should I have my wings3d model in the same directory as all my exports for simplicity? I was trying to keep things clean by exporting obj into an obj subdir, collada into a collada subdir, etc.)

When I right-click "import new assets" in unity, it lets me select the obj but not the mtl. (and if I drag the mtl in from Finder, Unity doesn't know what sort of thing it is). And It doesn't let me select more than one thing (so I can't select the obj and the textures together).

If I drag the obj and textures in, I can open the imported obj and manually assign the textures, and the UV looks correct, but that's kind of a pain.... (actually, it looks like everything is disconnected enough so that so long as I leave my updated materials inside of unity alone, I don't have to worry about them being overwritten by new imports...)

Possibly related/unrelated... I have 3 copies of an object in wings3d all using the same material/texture, but when exported to obj and then imported into unity, they all get new materials (in Wings3D I have one material, Rod, and one texture, Rod_auv.bmp, .... with objects Rod1, Rod2, Rod3, and Rod4. In Unity, they get materials Rod1_Rod, Rod2_Rod, Rod3_Rod, ... should I be naming all four objects "Rod"?).

Sorry for the barrage of questions, and thank you!!
