I have a cloud object that has the brightness, grayscale and luminosity effects. All the object instances are in the same layer. I have a day/night cycle and weather states that affect the effects same way equally to all instances (meaning that I could potentially use the effect in the layer instead of the object) but I also have set up conditions that affect some instance effect levels individually (clouds get individually more grayscaly as they move in distance and get a brightness flash with lightning etc.).
So I could apply many of the effects' intensity levels to the objects' layer, but I couldn't replace the object's effects completely this way. would it still likely improve performance? I read in performance tips that you should render same effects in the same layer, I'm not sure how that applies in this case.
