Enigma Re-Skin???
Try going into the matrix upl file and copy and paste everything after [Public] , then Re-name the new copy to whatever you want, for example:
Player=(DefaultName="Matrix_Enigma"
Then paste this over the body-skin section:
BodySkin=UT2004PlayerSkins.Enigma_Body
Unfortunately the wing texture is tied to the face skin, so if you change the matrix face to the enigma face texture the wings go black; depends on whats more important to you, having enigma's gold face or good looking wings.
Make sure you re-name the model so it does not conflict with the original.
You can have both versions, they just can't be named the same.
And yes you can do this cheap ass kind of skinning with other models; most do not line up well. Try changing the Death in Trax hoverbot model so it uses the Corrosion body/face skin that comes with the game. Or the Dreadnaught model looks really cool with the Exile Xan skin for the body and the Sidonious skin for the face. Hope this helps your skin cravings; Have fun and peace
