Maybe there's a better way to do what I'm doing: I made some bars using the 8-sided cylinder brush. However, they have a shiny texture, so I'll have 40 tiny, close together faces that each need a cubemap; It'll be a total mess. I'm just wondering if there's an easy way to do it, rather than ctrl+shift to copy a cubemap, then reassigning it to another face. Is there a way to attach one env_cubemap to an entire brush? Or maybe I could either find another way to make the bars, or simply make them a different texture. Also, will I ever need to adjust cubemap size for anything?
