Second set of UVs (WLE 0.9.x)

I read on discord that lightmaps are now supported through a second set of UVs.

I am wondering if this capability is specifically for lightmaps or could it be used for any content ? For example decals

Hi @yin-chien_Yeap !

If you build custom shaders, it can be used for anything!
Detail maps (normal or specularity maps) on top of a tiling texture could be a great use case.

For decals I am unsure how the second UV-set helps, since those are usually textures projected by a bounding box? We are definitely also going to support decals eventually.

Hope that helps!
