hmm I find that odd, since inside of the material function it does exactly that already. The radius and diameter outputs all come from the same math. I did notice some unnecessary math that could be optimized to save a few instructions (that is if the compiler isn’t already figuring that out which it probably is).
So far I am unable to reproduce any blinking even without the “max” node.
btw you probably just want to use “result 0-1” unless you actually need the exact radius. i dont think thats what you want though.
