I guess you remember that CS:GO SDK in tools section... This night I made it work. Which means that Source SDK is brought back to life since it is possible to use all-new CSGO models and textures (idk about scripts, late night here, haven't checked yet). For now I can present few screenies:
Some of things on screenies seem not much legit (shadows for example, that are complete darkness), I apologize, too late for me to put an effort in it. I have important exam tomorrow so after I pass it I will try to discover/show you something better
