It would be nice to be able to bake the Digital Human Eye shaders, such as changing the color of the iris, to the base map like you can with skin and hair. Right now, a character can be created with edits done to the eyes in the shaders, but when it is exported (like as FBX format) the eye color reverts to the base map color with no shaders applied. It can be difficult to reproduce the shader values via an image editing program, so having them bake to the base color map would be highly beneficial. As of now, models created in CC4 are only "compatible" with other Reallusion software such as iClone, as the color values for the eyes do not transfer like the shaders for the hair and skin do.

I enjoy using the material shaders native to CC4 as it cuts down on the amount of time I have to take fiddling with materials outside of the program. Having to make custom base color maps for each of my 100+ characters would be extremely time consuming and cumbersome to keep track of.
