vmap_backmaterial

Syntax

vmap_backMaterial

Overview

This allows a brush surface to use a different material when you are inside it looking out.

By way of example, this would allow a water brush (or other) surfaces to have a different sort order or appearance when seen from the inside.

vmap_backMaterial only works on brush faces. For this reason, it is often deprecated in favor of using vmap_cloneMaterial where the target material contains vmap_invert.

It can still be useful as a kind of shorthand.
