how do i add skin bodygroups for a model?

i was wondering how do i add skin bodygroups to a ragdoll?

For alternate skins, add this to the QC:


$texturegroup skinfamilies
{
 { "ORIGINALTEXTURENAME.vmt" }
 { "ALTERNATETEXTURENAME.vmt" }
}

Add a space and another texture name like so if you want more than one texture to swap between skin sets.


$texturegroup skinfamilies
{
 { "ORIGINALTEXTURENAME1.vmt" "ORIGINALTEXTURENAME2.vmt" }
 { "ALTERNATETEXTURENAME1.vmt" "ALTERNATETEXTURENAME2.vmt" }
}


$bodygroup BODYGROUPSETNAME
{
 studio "BODYGROUPPART1.smd"
 studio "BODYGROUPPART2.smd"
 studio "BODYGROUPPART3.smd"
}

Add as many “studio” entries for the amount of bodygroup parts you’d like to use, and add another one of those $bodygroup entries if you want another, separate set of parts that you want to swap out. A quick way to have a “none” option would be to add the “skeleton” SMD to one of the “studio” options in the specific group.

oh ok thank you for the help!
