I add a FxaaPostProcess and a HighlightLayer on my scene and notice FPS will drop when they enable meanwhile. But in fact, I don’t want the FxaaPostProcess to apply to the HighlightLayer, is there some way can do it?
The post processes don’t apply on a specific layer, they apply on the framebuffer in the order you declared them. What you can only do to save some performance is to disable/remove some post processes so they are not applied at all.
Ok, thanks a lot!
