Func viscluster

A VVIS-optimising internal brush entity available in the Orange Box engine. It allows you to manually tell VVIS that the leaves inside its volume can all see each other - useful for large open areas where the computer's calculations would otherwise take a very, very long time to complete.

It should be textured with tools/toolstrigger.

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 reduces compiling time by letting VVIS avoid calculations. It does not change the location or the number of leaves. Use Func_detail, Hint brushes and areaportals to optimise runtime performance!
