Johnny Fehr covers the lookdev part of the skin displacement technique he uses to create a realistic skin material.

The ‘uncanny valley’ is still a thing for realistic characters. Part of the solution is to create the best, most realistic skin shaders and textures to move past that valley. Here, Johnny Fehr shows how to make the best-looking and photorealistic skin displacements in lookdev mode.

Fehr uses Houdini and RenderMan in the video, but the techniques could easily be applied to other DCCs once you understand the process.

While on the topic of displacements, Johnny Fehr showed a layered workflow a while back that uses Displacement Maps and a layer node that offers a way to get more details in your textures. Visit that tutorial here.
