Texture applier tool
The Material Tool or Material Gun is a mode for the Tool Gun that allows its user to apply to the total surface of ragdolls, NPCs and props a new texture.
To select the Paint Tool, hold and press the menu key (which is Q by default), in the tool list select in 'RENDER', "Material". The game will automaticly switch to the tool gun which is now in Material Mode.
To select a texture, hold and press the context menu key (which is C by default), then select the texture that you want to use. You can also select one from the Q menu.
Abilities and useEdit
The Material Tool has two triggers. The first one (MOUSE1 by default) applies the selected texture to a prop, ragdoll or NPC. The second one (MOUSE2 by default) removes the applied texture and restores the original. (Update: R is now how you remove the applied texture)
While the Material Tool can do many things, it cannot apply textures to the map or to a non-entity surface and it can only apply one texture maximum per object; If applied on one which has already been retextured the old texture will be replaced with the new one.
