I exported a few meshes from CastleFortress to Maya, to study a little bit how it has been built.
Let’s take an example: Building_Segment_Tower_B.
Here the mesh in Maya. It is made of several subobjects combined together.
I had a look at the UVsets.
We have 2 UVsets, one for the UVmap and one for the Lightmap because it’s a static mesh.
As shown in the screenshots, the lightmpap is OK and is in the UV space [0,1].
What I do not understand is the UVmap.
It is not in the UV space [0,1].
Thank you for your help and explanation.
