View Full Version : obj export is missing UVs

03-15-2011, 03:27 AM
Here a simple model that doesn't export UVs when exporting as an obj file.
Does any know why or is this a perpetual Lightwave bug?
(win7, LW 9.6 win32)

I have applied the UVmapping to the surfaces.

If I examine the .obj export file, you can see that the metal surface only gets:

f 406//277 408//295 386//296 378//276 etc...

where the vt component is missing.

If I export as .DAE it works.
Any thoughts?

Export (metal surface) works fine on my end. Thats all i can say =/

Works here too. Lw9.6 32bit win7.

Did you set an image in your UV Map? If you just make a UV Map and don't put anything in it, it'll disappear on export. Actually, I sort of recall reading that you don't actually have to put an image on the UV, but you at least have to open the texture editor and select UV projection mode and select the UV Map.

Thanks for helping me guys!

I found the problem:
I had another model open in modeler, which was using the same surface name(metal) as the model I was exporting.... so therefore, when I exported to obj the exporter got confused somehow. The other surface may/may not have had the UVmap applied.

When I closed the other model, the obj exported correctly.

It's a bug, but glad there's a solution. Thanks again.
