Snappers shared a look at their own tool that allows adding facial details.
Snappers have recently revealed a new modeling concept (parameterized curve modeling) that lets artists create a full set of high-quality realistic wrinkle maps in a few minutes using Snappers Wrinkles Designer. The tool is a part of the Snappers Character Designer Suite. The team noted that the approach can work with any model regardless of the topology or the UVs.
Little is known about the output here or whether the team plans to release the toolkit for the community, unfortunately.
