I’m not sure how these work, but AI accelerates the refinement of realistic textures. As an example, we just switched to Metahuman for human rig building.

The devs building the rigs use real people, and Metahuman uses AI to actually increase their imperfections.

We then shift into Blender where we construct hair and clothing. The hair uses internal AI that accelerates the process of individuating hair behavior we then export into unreal where the hair responds to physics.
