Thank you!
The more I can learn about this the better. I have been considering Unity and CryEngine as alternatives, mainly for antialiasing problems, but it’s not clear if I’d fare any better than with UE4… currently I render at anything from 4K up to nearly 16K, in order to produce 1080 output. I’m fairly nervous of what happens when we have to produce 4K final output though, especially if there are hard limits on GBuffer size.
