I am sure this has been discussed before but I want to make absolutely sure since my artist is asking how many materials and what size before performance starts taking a hit?
Can he use 2 separate 2048x2048 materials on one character model without causing an performance slowdown due to an extra drawcall?
can he use 3? one for face, one for body, one for coat?
Or is it best to only use 1 material per character model?
