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 the frame in wire-frame mode that shows how much of the game world is being rendered, and how.

It has four settings (0-3).

mat_wireframe 0

Off. Do not display any wireframes.

mat_wireframe 1

Displays all triangles the engine is rendering. The world brush polygons are rendered in pink.

mat_wireframe 2

Shows a simplified view of triangulated world brush polygons in green, using a hidden-line style rendering. Should not be used for visibility optimization since it does not accurately represent the full vis set, but can be useful for a less-cluttered display of nearby geometry in view.

mat_wireframe 3

Same as mat_wireframe 1, but does not display triangulation of brush geometry. The world brush polygons are rendered in pink.

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

• Models - Cyan
• Sprites - Green
• Displacements - Green
• Decals and Overlays - Yellow

This variable is a cheat.
