Help With Bisurfs and RVMAT

[natanbrody 10]

Could someone explain to me what these are and how do I write them because the Mondkalbs tutorial does not help at all :(

Have a look in there. And follow related links.

Rvmats are the same thing as the materials you find in applications like 3ds max or Blender. They're applied to a face or group of faces, and tell the engine how those surfaces respond to light. They can contain references to specific textures like normal, specular and ambient occlusion maps.

Bisurf files can be referenced too. These can give the surfaces special properties. Like bullet penetration for example.
