Hey guys, so I am here trying to post process only on one of the sphere.  
Currently it happens on both of them.  
I read that you to do that, I would need at least a 2nd camera. I have added one (Free Camera), but I do not know how could I attach sphere2 to camera2 and show it without being PostProcessed (as it currently is in the demo).  
I tried to playing around with layerMask, but I just cannot figure that one out.

**Expected end result:**

- Sphere1 is post processed, Sphere2 is not.
- Camera 2 keep the same position/follows? as the first camera. So it looks like there is only 1. As camera1 is the main one.

P.S.  
What is my use case?  
I have some meshes that I would like to be post processed and some of them not.  
The Camera2 should be there only to show meshes/things that shouldn’t be included in the PostProcessing process

I appreciate any help :3

I used the 2 cameras that you already have with layer masks 🙂

That worked out! It finally starting to makes more sense after looking at your example. Thanks :3
