I want to create geometry with multiple (at least 2) UV maps. One of them will be used to map the base texture (from a texture atlas) and the other one will map a pre-baked lightmap.
I want to export the mesh including both UV maps to a PLY file.
In Blender, I added two UV maps and edited one of them to make them distinguishable:
Unfortunately, only the specific UV map marked as "active for rendering" is exported into the PLY file:
[...] property float x property float y property float z property float nx property float ny property float nz property float s // u property float t // v [...]
As PLY allows arbitrary vertex properties, it is not limited to only one pair of texture coordinates per vertex.
Am I missing something or is this a limitation of Blender's PLY exporter?
