Cavity Mask + Inflate brush
Would like to share one new layer I implemented on this character meanwhile sculpting and made a big difference in terms of breaking speculars and adding more variation.
The idea is to have enough variation on the skin using the displacement maps from texturing XYZ. Unfortunately is not enough, that is why is needed some extra love on the skin, giving several passes.
The new pass I implemented was "inflate". The idea is to bump certain areas where the skin is more dramatic, like cheeks and jowls. Eventually on the final render this extra bump helps a lot to break the speculars and give more realism.
1. Mask by Cavity
2. Blur Mask
3. Sharp Mask. I found out an extra sharp can help in certain occasions
4. With a very low Zintensity get the inflate brush and go around those areas where is needed.
