Thanks! The new DOF is incredible, and it is making is so easy to frame a good shot. It makes you wonder what other improvements are just waiting to be developed.
The tricky thing with Epic’s motion blur is reproducing pixels which are occluded by the subject which is moving. If the temporal buffer has no pixel history you get that blocky smearing. In my experience, if Epic cannot make a new method for art practical at real time frame rates, they wont invest the time. Hopefully that’ll change more in the future as more production companies get on board, but my method is way, way too inefficient to be considered for now.
Mutli sub frame motion blending might be feasible one day. If you compared the motion vector data over a period of time you could reduce the number of sub frames you need. Still very inefficient though. The current implementation is so good already.
Something interesting which just popped up recently is Nvidias DLSS toolset. Apparently there are reports that DLSS is helping fix temporal artifacts, by creating a kernel of “the way your game looks.” It requires devs to submit their games to a server to get crunched, but the potential is very interesting.
I think AI might solve our motion blur issues for good. Probably a lot of others too. It’s a good field to invest in.
