Hello everyone :-).
I’m trying to apply different UV mapping to a single mesh for their normals and colors.
Let’s say normal map for optimizing and making it easier to design, I prefer to use one UV map arrange. But for the color map I prefer to use another UV map arrange.
It’s possible in Blender, but on Three.JS I’ve found no clue on how to do it.
For example this basketball mesh:
It’s better to design the color mapping in a flat way (upper UV arrange), so it’s easier for someone to draw a design on the Basketball. But to apply normals, roughness, metalness, etc. I find it more convenience to do it as the bottom UV arrange.
How could I tell on Three.JS that the normal/colr/roughness/etc map should use one UV map or the other.
