How to optimize… what? Shaders? That all depends on the nature of the conditions; there’s not a magical way to optimize conditional logic.

For example, if those conditions are based on values that are compile-time constants, there’s nothing to optimize. Any compiler worth using will make them disappear.

thank! yes, optimize the shaders.
but the conditions are not constants, eg. else if (uv.x < x1 && uv.y < y1), etc…
