Rebuilt PedFuncs v0.3.1 beta specially for GTA 3. Skins adaptation is done as for SA.
It is necessary to create additional textures in the TXD file. If the name of the original skin texture is "copnu", then create textures with the names "copnu_remap" or "copnu_remap2" (3,4) It does not matter what you write after the "_remap", but its presence is required. Everything is very simple!
In the archive with the plugin there is a test skin for the cops. Modloader required.
