Hello, I just say, most 3D CGI programs can be used to create a digital make-up on the characters or even chroma screen actors. With proper depth, movement, and texture, such can be used to create photorealistic or surreal elements needed by any bigger element. Unusual texture maps can also be done by placing any type of texture map across the surface of an element, which opens endless possibilities in creating the final element. One timely example of how the technology has improved these days is how Avatar showcases characters with blue skin. thanks!~ Rachel T.
