Yep, understand about using it to drive other things. Was more so just interested to know if it mattered if passed in values like 1.8 to Roughness or 2.4 into Opacity for example. I’m assuming the UE4 inner workings would cap these values to 1.0 anyway, but was just interested to know. So you are saying that the inputs for Roughness and Opacity are clamped to 0-1 internally, which would answer my question?
That’s an interesting node. I use clamp a lot to keep values between 0-1, but saturate sounds even better. Thanks for this tip.
