Custom models(skins)/textures/voices will not work on pure servers. Some skins includ hacked view models. They are not recompiled, but only a simple hexing tweak. It should not cause any instability issues. Due to the size of the heads in proportion to the bodies, the head hitboxes can be a bit decieving. When attempting a headshot, aim for the face area; the vibrant hair color should provide a good frame for your target. Our skins do not contain hwm models. For your convenience, if you happen to join a pure server(after leaving an non-pure one) and see custom models being invisible, type this in the console "mp_usehwmmodels 1" and it will reload the official models into game. Simply type "mp_usehwmmodels 0" when you join a non-pure server. Contact us if you have any problem browsing our web pages or if you want to have a custom player model for the game. I(personally) am always open for any kind of modelling-related jobs(please send me an email about the request and try not to post the message on our steam group page/chat room). Thanks.
