For a future update to Character Creator 4, I think that it would be quite helpful if a couple of parameters were introduced that could give artists the capability of either generating a new character completely at random using the artists' entire material/asset library, or by giving the artists the ability of selecting a narrow group of characters from CC's character library that CC could then draw from to procedurally generate completely new variations of certain characters.

From there the artists could save these variations as brand new crowd characters that can be re-used for as many new projects that involve crowd scenes as they could want down the road. This way the artists wouldn't have to do a lot of additional work to make the crowd character models that they might have downloaded from outside sources match their personal artistic styles, and/or the visual style that they have established for their projects.
