    I want to discuss a problem I've encountered today.

    after using my trusty buildcubemaps, I noticed there was still some checker of death on some reflexion. after looking a bit closer into this, I figured out these checker were reflections of other reflective materials. a window reflecting an other window in this case, the reflected window had checkers on it while the actual one was looking fine.

    I started looking around for some solution and guess what! running the buildcubemaps a second time did the trick!

    it kinda feels wrong tho. feels like I'm forcing my way into this. is there really no other solution than having 2 iteration of buildcubemaps?

    because loading the map, building cubemaps, reloading the map, building cubemaps again and reload is a pain in the ass imo

    mat_specular 0 before you build cubemaps. This disables the "purple and black" cubemaps before taking all the screenshots to build new ones.

    Doing it a second time diluted the "purple and black" out, but its still there in trace amounts.

    It took me awhile to figure out myself. :blushing: I was doing 4 times to bleed out as much as I could in very shiny areas.

    the right way to do it, really, would be to kill specular and then run it twice anyway. its a little anal, but building cubemaps is so easy, why not?

    You only need to build them once for each HDR setting, as outlined here.
