CSTRAD

An advanced compiling tool that acts the same as VRAD in that it creates the lightmap data (created through radiosity lighting) that will light your map.

The CSTRAD Tool can be skipped to create an unlit map, however the use of the other 2 tools CSTBSP and CSTVIS is recommended for maximum performance.

The CST series are now depreciated and do not contain the newest HDR features. The developement has stopped for now.
