Flickering emissive texture with drivers?

Hello, just a question about controlling values using drivers. I’m working with an emissive screen on an object, and I want to make the screen flicker slightly.


Can this be pulled off with drivers or some other technique, or will I have to keyframe the values manually?

Yes, you can frame rate at the driver, control the speed with divide/multiply. Then use sin/cos, round, random or anything that works for you.

I tried drivers, but I want it to flicker as if it was a broken or damaged light. With drivers I have only figured out how to increase the value at a steady rate and/or accelerate to higher values, but I don’t know how to make it jump back and fourth between values.

Yes and I suggested the methods. I think you need some examples: untitled.blend (779.7 KB)
