Is it possible to combine displacement maps? For example, a displacement map extracted from a Zbrush sculpt and a tiling microsurface map. Both maps are 32bit.EXRs.
In Arnold it can be done by normalising the range of the microsurface map to zero(to match the Zbrush map at zero) using a alRemapFloat node, and then layering the 2 maps with an alCombineFloat node set to Add.
