It would be killer if we had the possibility to select UV source for the MASK and VFX texture aswell
Right now that option is shared between MCR, MASK and VFX.

Benefits:

1: You could use MCR och NMO on UVset1 with mirrored UV's to keep the texel density quite high.
2: Enables us to create a uvset only intended for MASK and VFX without mirrored UV's
