PBR (Strata shader)

Stub

This article or section is a stub. You can help by expanding it.

PBR is a Pixel shader available in Strata Source.

Warning:

• The {{{game}}} parameter is inconsistent with the name defined by the {{Strata}} template. This can most likely be fixed by setting the value of the {{{game}}} parameter to Strata Source.
  If a parameter is consistent but you're still seeing this warning, it may be an issue with the template itself. Please discuss it on the template's talk page.

It uses many different texture maps to create a more accurate simulation of light. Strata Source uses a modified version of Thexa4's PBR shader, which is capable of rendering lightmaps on brushes. It can be used on both brushes and models.

Note:Similar unrelated PBR-based shaders are also used in Titanfall branch and Source 2.

Note: Alien Swarm: Reactive Drop with Strata Source's permission, have ported the shader. ( Commit link )
