After testing different possible solutions, I decided to just go with spatial samples in my render settings in MRQ. The difference of quality on the motion blur and DOF is almost unnoticeable, at least for the shots I am working on. This has been a huge headache, not sure why epic is not fixing this since it has breen broken since 4.26. I also tried baking the cache of my cloth to be able to use temporal samples in my render but the Chaos Cache plugin is super buggy. Anyway, I used 1 temporal sample and 32 spatial samples for my 4K render and it worked fine, so that’s the way to go until they decide to fix this. One day Epic may give us a fully stable version of UE… hopefully.
