This is weird.
I compile my level, the cubemaps are all bright white as I havnt run buildcubemaps yet. So I do, reload the map and its still shiny white everywhere.
I put sv_cheats 1 on, buildcubemaps, change level, change level back. Still shiny.
I try closing the game, reloading game and map, still shiny white.
I'm doing this in Ham and Jam, SourceSDK has the -ep1 thing added and the .bsp size has increased after buildcubemaps has been run, what the funk is happening.
