func_viscluster
func_viscluster
is a internal brush entity available in all Orange Box games. It allows you to manually tell VVIS that the visleafs inside its volume can all see each other and should be treated as one. This is useful in large open areas where visibility calculations would otherwise take a very, very long time to complete. Poor use may be expensive for in-game performance. It should be textured with tools\toolstrigger
.
To do: Does it reduce map filesize or just increase in-game performance?


mat_leafvis
show the leafs to still be intact.
func_viscluster
on the other side. Never allow a func_viscluster
brush to cross a water plane, or very strange things happen.
