KMQuake2 0.20 supports scripting for md3 and md2 models on a per-mesh, per-skin basis.

The name of the script file is the same as the md3 or md2 model, but with a .script extension,
e.g. the script for models/mapobjects/gargoyle.md3 is models/mapobjects/gargoyle.script

Inside the script file, the scripting parameters for each mesh and skin is enclosed in
curly braces, proceeded by the skin name formatted as <meshname>.<skinnum>
For md2 models (which only have one mesh), the meshname is always md2mesh.

For example, if the mesh name to be scripted for is gargoyle, and the skinnum is 0
(the first skinnum), the skin name would be gargoyle.0

Here's an example of scripting parameters for this skin:

gargoyle.0
{
noshadow
nodiffuse
envmap 0.15
}

This script specifies that this particular skin is to cast no shadow, not be vertex lit,
and be envmapped with a translucency of 0.15.

If the mesh has a second skin that a different effect is desired for, a set of parameters
can also be scripted for that skin:

gargoyle.1
{
noshadow
trans 0.6
scroll 0.5 0.5
}

This makes this particular skin cast no shadow, have a translucencly of 0.6, and scroll
0.5 units on both the x and y axis.

Here's a list of parameters that can be used on skins:

twosided				- makes this skin render as two-sided.
alphatest				- makes this skin render with alpha testing enabled (requires alpha channel).
fullbright				- makes this skin always be drawn at full brightness.
nodraw					- makes this mesh not be rendered for this skinnum.
noshadow				- makes this mesh with this skin not cast a shadow.
nodiffuse				- makes this mesh with this skin not vertex lit.
envmap <value>			- makes this skin be envmapped with a specified translucency between 0 and 1
trans <value>			- makes this skin be tranlucent with the specified value between 0 and 1
alpha <value>			- same as trans
blendfunc <type>		- sets the transparent blendfunc for this skin- add, filter, or blend, 
blendfunc <src> <dst>	- similar to above, but uses a specifed combination of src and dst blendfuncs.

glow <imagename> identity	
						- draws imagename as a fullbright glow over the texture
glow <imagename> wave <func> <base> <amplitude> <phase> <freq>
						- draws imagename as a glow over the texture, brightness controlled by using
						func waveform (sin, triangle, square, sawtooth, inversesawtooth, noise)

tcmod 					- supports most of the tcmod functions that Q3 shaders do

tcmod rotate <rotspeed>	- rotates the texture by rotspeed degrees

tcmod scale	<xScale> <yScale>
						- scales the texture by x and y factors
						
tcmod stretch <func> <base> <amplitude> <phase> <freq>	
						- stretches the texture using func waveform (sin, triangle, square, sawtooth, inversesawtooth, noise)

tcmod turb <base> <amplitude> <phase> <freq>	
						- warps the texture (base is not used)
						
tcmod scroll <xScroll> <yScroll>	
						- scrolls the texture by x and y
