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