When Having a SkeletalMesh or Static Mesh, you can control Material Parameters directly. Something like that is missing for Post Process Materials.
Matinee had a generic Float or Vector Track.If Sequencer had these kinds of Tracks as well it would make things a bit easier. Level Sequences have a Director Object, someone could drive Post Process Materials with that.
This was reported and tested in 4.21.2 (CL-4753647), This was reproduced in 4.22.2 (CL-6574378), 4.23 (CL-7021509), and Main 4.24 (CL-7039453)
Results: There is only a Weight track which controls the Post Process Weight.
Expected: Tracks for every Parameter in the Post Process Material
There's no existing public thread on this issue, so head over toAnswerHub just mention UE-76366 in the post.
