Func viscluster

A VVIS-optimising internal brush entity available in the Orange Box engine. It tells VVIS that the leaves inside its volume can all see each other - useful for large open areas where the VIS calculations would otherwise take a very, very long time to compute.

Warning:The brush should not cross the surface of a water brush. If it needs to, create a separate second entity on the other side.

Note:This entity only reduces compiling time, and does not affect the map when it is running. Use Func_detail, Hint brushes and areaportals to do that!
