I tested what you suggest and it didn't change anything unfortunately, I installed the update for my nvidia 3070 card on my 3 computers and they all have the same problem,,
what is very strange is that even the compressions that worked no longer work.
I have 3 computers that compress in iray, I have made a lot of videos in iray and have never had so much trouble maintaining it, can I download the older version of iray?
ps. I don't understand that it's just me having this problem when I have 3 computers to test and none of them work to do something I've been doing for years.
