I have a LightWave file that contains a racing track, without texture. When I tried to apply one in Blender using Unwrap it appears well in Blender, but when I exported to M3G it results very different. The same happens when a import a 3DS file that already has a texture.
I already tried marking the seams manually, but it didn't work. I also erased the materials and added new ones, but that wasn't the problem.
I really don't know what the problem is, so I would appreciate some help with this.
