Now that is a valid reason. I was speaking out more towards those that just seem to be jumping on the complaint wagon, without a solid reason.
As for your marketplace content, couldn’t you update your packages? I dig your work, and I’m sure it would be a pain… But it’s the price we pay with such a feature filled engine. I think Epic does a pretty good job of not “breaking” things, but sometimes it can’t be helped. Still, with the amount of people complaining about the tonemapper, I wouldn’t be surprised if they reverted that change.
