I'll try that to see if it works but even if it does work it doesn't solve my problem. If that works it'll strip off ALL textures whereas I only want to remove the lightmap textures, retaining the main color textures. Good idea though; any others?
EDIT: No go. Using a blank brush has no effect whatsoever. Well, it does have an effect when you use PaintMesh (as opposed to PaintEntity) but as I expected it stripped off all textures, not just the lightmap.
