Tool textures (Source 2)







Tool textures are used, mostly by the entities they're named after, but sometimes by parts of the engine such visibility calculations, to perform special tasks. They can be easily found in the Asset Browser using "tools" (or alternatively, in Counter-Strike 2, click the Edit filter () icon and type "tools", then click Tag "Tools Nodraw Material" or simply type "tag=@vmat_tools_nodraw", or in Half-Life: Alyx/older Source 2 games, click on "X/X Tags", then check Tools Nodraw Material) as a filter. However, like Source, some tool textures may be located in different directory (e.g. dev or effects folder).
