DP GFX SKINFILES

From Quake Wiki

Alias models (mdl, md2, md3) can have .skin files to replace conventional texture naming, these have a naming format such as:

progs/test.md3_0.skin
progs/test.md3_1.skin
...

These files contain replace commands (replace meshname shadername), example:

replace "helmet" "progs/test/helmet1.tga" // this is a mesh shader replacement
replace "teamstripes" "progs/test/redstripes.tga"
replace "visor" "common/nodraw" // this makes the visor mesh invisible

It is not possible to rename tags using this format

Or the Quake3 syntax (100% compatible with Quake3's .skin files):

helmet,progs/test/helmet1.tga // this is a mesh shader replacement
teamstripes,progs/test/redstripes.tga
visor,common/nodraw // this makes the visor mesh invisible
tag_camera, // this defines that the first tag in the model is called tag_camera
tag_test, // this defines that the second tag in the model is called tag_test

Any names that are not replaced automatically show up as a grey checkerboard to indicate the error status, and "common/nodraw" is a special case that is invisible. This feature is intended to allow multiple skin sets on md3 models (which otherwise only have one skin set).
