In unity docs I read "
TEXCOORD1, TEXCOORD2 and TEXCOORD3 are the 2nd, 3rd and 4th UV coordinates, respectively.What does that mean - the index at the end?
Thanks!
Texcoord0 is the default 2D coordinate system for UV's
starting at U=0 and V=0
Texcoord1 would be the next set of UV coordinates (especially in UDims)
Texcoord2 would be the next set of UV coordinates... etc.
hope this helps
