I wish I had a solution.
I am also running into this issue. I am new to this type of content and I find it crazy with the popularity this is receiving there isn’t more info out there.
I have been running test on shot footage and some stuff I made in AE the past few weeks. If I find anything that works well I will let you know…
Also I am concerned that the higher res stuff won’t work for headsets since they can only take ~2k. The best thing I have found to do so far is set the res higher but that just won’t work for those. I don’t know how other developers are making the content look so good in 2k.
