O.K for people who dont know how to put character md2 in srb2, heres how you start off. You need a srb2 folder with all srb2 stuff, a note pad, a md2 folder, a md2.dat, and opengl (make sure the md2 folder is in your srb2 folder. And your notepad in your md2 folder. Also make sure that the md2.dat is in the srb2 folder, NOT in md2 folder!)
step 1 download the md2 that you want.
step 2 put the md2 in your md2 folder.
step 3 now to activate it you have to get a code for it, for example like "PLAY.md2 3.0 0.0" or something like that.
step 4 now put the code in your notepad.
step 5 now yor skin has to be named "play" and your md2 for your model for the skin is named "play.md2".
step 6 open up your srb2 net launcher and have it in opengl.
step 7 now once you get to screen open up the console and put gr_md2 and voula you have your md2.
If you still dont get it, oh well. or I guess I made a mistake somewhere.
