Optimizing the shader: when to replace If statements by a Lerp?

[werwack]

Hi Ryan,

Thanks for the answer.

I can suggest though, that if possible you use Static Switches for anything that can be turned off completely. That will definitely help your compile times by creating more permutations and only computing the used ones.

I still have some trouble to understand this notion of Static Vs Dynamic.
For example, as shown on the picture below, my input is a float used as a boolean: if it is strictly inferior to 1.0 I do one thing, otherwise (so if it is true) I do another.
Should I use a static boolean instead?
