I’m getting a warning when building my lighting saying: Run ‘Clean BSP Materials’ to clear N unnecessary material references. Looking in documentation it says that option to do this is under tools menu:
However, I can’t find any tools menu! Am I being a tool? Where is menu/option?
Is there any chance you could throw up a screenshot showing where this is in GUI? I have same error, but cant find it in Mode selector. Is BSP advanced editor available off of Geometry Editing Mode?
