I created a simple mesh, UV and texture in Wings3D and imported it into Unity. The mesh imports fine, but the UV’s seem to have been lost. If I import the same model into Carrara 5 Pro, it works fine. Not sure if I did something wrong or if it’s a bug. Attached is a zip file with the model.

Keli seems to have run into the same issue: http://www.unifycommunity.com/wiki/index.php?title=ObjExporter#Caveats (See Caveats)
So perhaps you are not alone and it is indeed a bug.

Thanks Jon, bummers 
I guess the work-around is to import the file into Blender and save as a .blend before importing into Unity.
At the moment when exporting an obj file you have to export an mtl (material) file for the uv coordinates to come through.
Can’t wings 3d export to fbx?
Wings exported a .OBJ, .MTL and .PNG file, but still no UV info in Unity.
Well I thought it did (I haven’t played with Wings in a while), but apparently FBX support isn’t in the current OSX Macintel build.
When I import .blends, the UVs get assigned to the wrong places, and some of the models’ faces disappear. :M
Hmm…I’ve imported dozens of .blends, and they all worked fine, so I suspect that some of your normals are flipped. If you turn off double-sided drawing in Blender, it’s easier to see when you’re having normal problems. (As opposed to abnormal problems. 
) Or turn Draw Normals on in edit mode.

Somtimes in Maya I find theres the odd triangle that doesnt render in Unity, but I guess if I tidy up my geometry modelling that will go away-and of course checking normals

On second thought, I do remember having a bit of a problem with one of my .blend files not importing 100% correctly. Converting quads to triangles fixed it though. Apparently Unity and Blender don’t quite always agree about the best way to convert quads, so if you force the issue in Blender then it doesn’t leave any room for misinterpretation.
