XNA Quake 6^th August 2007

Switch to custom shaders - a custom vertex format feeds in diffuse and lightmap texture coordinates.

Lightmap textures only.

Result = Lightmap * Diffuse

Simulation of software Quake 2 by using greyscale lightmaps.

Pixel shader used to ripple the texture.

A pixel shader can be used to convert a palette index and brightness into a colour via a colour map texture.

The 8-bit look mimics software Quake.
