Materials: VMap Commands

vmap_lightmapmergable

Syntax

vmap_lightmapMergable

Overview

When specified, the compiler will attempt to merge all surfaces using this material together onto lightmap sheets. This can drastically reduce the artifacts occuring on surfaces like terrain where precision issues might get you black spots along the lightmap seams. Definitely use this across large collections of surfaces on which you expect smooth transitions.
