Yeah the reflections is definitely the biggest that I have with the at the moment… screen space reflections are not gonna cut it here, you can improve them a bit by increasing the ray count in one of the .usf files but it comes with a cost and the result will be still far from accurate or clean.
Not really that much that we can do right now, it’s up to Epic to implement a better reflection system (it has to happen eventually but the question is when).
Anyways, I think I’m just about finished with the post process material:

It looks better in motion with the distortion and all 
There are still many things I wanna add (like god rays and lens splashes) but will have to do for now.
I still need to fix a few things in the material and plugin code before the release but it shouldn’t take too long, maybe Friday.
