I'm in a desperate need of someone able to properly tell me, the exact process, word for word, on how to build cubemaps for CS:GO. I tried everything, to deleting the 'Texture' files before building them (which always messes up the BSP with Pakrat), to building them after packing, but that doesn't work because almost 95% will not show the actual cubemaps... what do we do first, packing or building cubemaps? Please, someone take me out of my misery.
The best result I could find so far is the rebuild the cubemaps after I already built them first before packing. After I packed all my stuff, the default cubemaps (from Vertigo I think) returned. So I can rebuild again, but what it does it rebuils the cubemaps WITH the vertigo reflections. I don't want that, I don't want gibberish programming-bug visuals in my map. And, mat_specular dissappeared forever now apparantly...
