Mat wireframe

Mat_wireframe set to 1. Note the tree is being drawn by the engine even though it is behind the wall. This is an example of visibility issues.

A console variable that (when active) renders a wireframe that shows how much of the game world is being rendered, and how.

It has four settings (0-3).

mat_wireframe 0

Do not display any wireframes.

mat_wireframe 1

Outlines all rendered world brush polygons (in pink). (This setting outlines hidden polygons as well.)

mat_wireframe 2

Outlines all visible world brush polygons (in green).

mat_wireframe 3

Outlines all rendered visleafs (in pink).

No matter what active mode, the non-world brushes always use the following wireframe color codes:

• Models - Cyan
• Sprites - Green
• Decals - Yellow

This variable is a cheat.
