While going through a GPU pass, film setting in post processing isn't working as expected. This does not seem to be GPU specific
The displays should resemble the images in the documentation - PPE Doc
Displays that are effected are 1.2 - 1.15 - 1.16
Rendering update to default Post Process volumes may have changed/removed film settings and were replaced by Tonemapper
This is a Regression from 4.14.3
Result: No visible change
Expected Results: The color changes as if there is a film over the camera. Different color films for each volume at 1.2 display
There's no existing public thread on this issue, so head over to Questions & Answers just mention UE-40830 in the post.
