== Material Shaders (matShad; CD7FE87A) ==

This is not really a spec per se. But more of an idea of their purpose.

Generally speaking, they're just low level commands to the video card and assignments which the [http://www.sims2wiki.info/wiki.php?title=TXMT TXMT] files can call on.

There're a few kinds of material shaders.
These shaders can be VS(Vertex Shader), PS(Pixel Shader), just a simple material definition (just like a txmt file), TOC (Table of Contents Tree), and others.
For instance,
"pixelshaderwalls_PS2WallRendering" actually has definitions about the graphical structure(s) of the "wall" we see in-game.
"wall_Shaders for Sims 2 walls" actually has defintions about different sorts of "walls" such as the poolwall surface, wallmask, etc...

[http://www.sims2wiki.info/wiki.php?title=TXMT TXMT] files have lists of properties and type. Those properties and types inherit function(s) from the definitions in Material Shader.

For a particular material type, whether a material type of a txmt file can over-ride the preset values in matShad depends on whether the corresponding definition(s) in matShad has a sign "$" in front of the corresponding parameter(s).  That sign is to direct the game engine to take the local value(s) from a particular txmt file.

The scripts were custom-designed by maxis and are often mostly assembly code.
