Advanced masking techniques

Not only Object IDS and designated matte renders can be used for masking – UVS, Normals, Rest and World Position data, Ambient Occlusion and pretty much any technical pass imaginable make for great matte tools too. Render elements can be keyed, graded, inverted, added, subtracted or multiplied just to name a few common adjustments – all to arrive at the perfect matte for the exact area we want to manipulate.
