We have 2 cameras, one is the fight camera for rendering the 3D scene game objects and the other one UICamera is for rendering the UI stuff.
On the fight camera, there is a post process effect working on it for the blooming effect that will cost more 6~7 ms when 2 cameras are working together even if the post process effect doesn’t work on the UI Camera. If the UI camera is closed, there is no more cost any more.
Could any one help on it for solving this issue? Or is it a potential Unity rendering issue? We must use the UICamera for there are some particles displaying over the UI elements.
