I setup infinite PostProcess. I enabled Film Grain. I can see that it is shown in the perspective viewport (screen right) one (exaggerated values for testing) but the effect is not visible in the camera viewport (screen left). Any idea what that is the case?
The left viewport is controlled by cine camera in a sequencer.
Check the Post Process settings inside the Cine Camera itself, maybe you have overridden the film grain settings there. It could be the priority of the Post Process volume placed in the level as well.
