Thanks!
I was aware of Peter’s response on Lift Gamma Gain, I was waiting on one more piece of confirmation. Nick Shaw had also mentioned this issue in the comments.
I’ve updated the Part 4 article and the video to clarify the 1.02 vs 1.03 issue.
ACEScct released as part of 1.03 but seems like BMD decided to implement it while 1.02 was current and based on a commit to ACEScct that had been made earlier this summer.
