^ just a heads up, transparent textures aren't allowed. You can wear them for some replays or etc.. but they aren't allowed in a real vs. match.
That's not completely true. There is a certain percent of the texture which can be transparent. I don't remember how much, around <30%, like some rare set textures which use that transparencies
Yeah just turn off textures in the options, press esc, and go to setting or options, or whatever it is. Then go to advanced in the bottom left and uncheck textures and it will turn off all but the head texture.
