View Full Version : MudBox - Lightwave Baker?

12 December 2007, 10:17 PM

Im new with Mudbox 1.0. I make a base object in Lightwave and make an UV map for it. Then I save it as an OBJ-file and send to Mudbox. I do the sculpting and then try to bake the displacement to LW. IN the Baker, when I "Start Operation" it gives a notification "Texture coordinates are invalid". What could be the problem?

Did you assign a texture to that object before exporting it from Lightwave as an OBJ?

Lightwave won't export UVs with an OBJ unless you tell it which UV set to use. You do this simply by applying a dummy texture to that UV set. I hope that makes sense.

If you already sculpted on the mesh then don't worry, all is not lost. Just do the above and load that OBJ into your Mudbox scene and select that as your low poly version when you run the displacement baker.

Lightwaves obj exporter is buggy with UVs from my experience even when you assign them properly. I recommend using a program like Accutrans to convert your .lwo to a .obj file to ensure your UVs are exported with the .obj. You can get AccuTrans here
