Hi!
Is it possible to make a shader that won’t be affected by fullscreen image effects, or just one particular effect?
Thanks!
An image effect applies to a rendered image. So when you add a blur to your camera, it will draw the scene as normal then blur that image. You can’t exactly make a shader or object that ignores an image effect, but you can use command buffers or custom render queues to make sure your object is drawn after the image effect is applied so that it can’t affect that object.

Another thing you can do is draw to render textures; anything that you want an image effect applied to goes to to one render texture, and the rest go to the other. Apply the image effect to your first render texture, then render them both to the screen. This will be tricky if you’re not savvy with the graphics pipeline because you’ll likely need to share a depth buffer between render textures to make sure objects that should be obstructed from the camera view aren’t rendered on top.

You could also use the stencil buffer to mark pixels that should be skipped. It depends on the full screen effect whether this leads to the desired result. It would work for a color grading fullscreen effect for example.
