"Bump mapping is a well known but old technique for faking 3d reliefs. The relief information is stored in a gray-scale image. But a new and very popular method in the 3D game industry offers to store the relief information in a RGB image, increasing the precision and, obviously, the realism of fake reliefs on your 3D models: Normal mapping. This short tutorial is about showing you how to build your own Normal maps without expensive tools, and of course how to use them." (source: feeblemind.tuxfamily.org)
MH Tutorial: using the SubSurface Scattering script - "This tutorial aims at showing how works the SubSurface Scattering Script of the MakeHuman project. The script is a different version of the Superficial Scattering script already featured on ::feeblemind.org::, and, as it can simulate the translucency of the material, it gives more realistic results for such materials needing transparency to be taken into account."
