I read the discussion and they work perfectly but I have a couple of questions: How I can add the signal of safety car? I'd like it to be reported instead of the other flags and not as a separately light. Currently I replaced the texture of the green flag with a black Texture because With flags "turned off" stay green. Is it possible make them green where it is needed and completly off when they do not report anything? If I add a frame 12 (with turnoff texture) and put into the material (12, 0, 1, 2, etc...) might work? Thanks
