The countertop laser tool is perfect for your workshop

draws all textures for the aera you are currently in. the game is based on brushes which are allways drawn when you are in a certain area. it might not draw all models, but counterstrike uses few models and mostly brushes. this is how our "real life" simulation works too. 1) run half-life on xash3d with -console parameter 2) type r_lockvis and r_lockpvs in console 3) look around and be amazed i've always thought that this is a great way to try and understand parts of the "double slit experiment". how
