ok man u wanna bS! around i dont have ur time give me specifics what game cs:cz cs:s, what do u play steam none steam?
www.forumplanet.com/counterstrike youd better ask them.. And I would think its possible through the source SDK?
u put the skins you dl in steam/steamapps/USERNAME/counterstrike/cstrike/models then restart steam itf you have it on and they should work! skins pwn!!
Milkshake 3d, get it off of download.com. You can make models with it(guns and players). And for maps get WorldCraft to make them.
firstly we need to establish what version your talkin about? dont confuse CS with Adobe CS what sort of things do u wanna skin? guns. ull need source sdk and possibly the xsi mod tool. im not sure of how to exactly do it, but ull need to open the model in the model viewer or 3d modelling program (xsi mod tool, 3ds max, milkshak w/e) and the apply new skins made in photoshop (u may need dds plugins)
