How costly are blend overlay materials for mobile?

Hi, I want to change time of day using blend overlay on all my materials. Is this costly for mobile or is there a better method to use? Thanks

generally you would adjust the lights for day/night cycles. Maybe you’re going for a particular look, or have some kind of game where adjusting light won’t work, so sharing more information about your game could be useful toward finding a better method.

depending on the look you’re going for a post processing material might work better, that would be a good bit easier than adding an overlay in each material.
