SSAO without normal can be made to work. SSR at lower quality can be made to work in the same way that SSR works on translucency in the deferred renderer. As to when we’ll get to these - hard to say as we’ve found they behave poorly in VR.

It behaves poorly without TAA, but with TAA it looks great, even in VR. Just TAA behaves poorly in VR. Thats why I asked about this:

Once SSAO will be supported in the forward renderer, could you maybe directly implement the blur shown here: Screenspace blur for SSAO [C++] - Rendering - Epic Developer Community Forums to the forward renderer, since the usual TAA blur will not be available? With that blur it should look great on lowest quality with MSAA.

It is looking very bad in VR because of these artifacts which are in screen space, so those individual points stay at the exact same pixel all the time, looks very wrong in VR:

&d=1470336062

But once it’s blurred, that problem goes away and SSAO looks great in VR:

&d=1470336112

What do you think about it? Shouldn’t be too hard to make that an integrated option for SSAO with MSAA or FXAA, right? The code is there, just needs to be integrated to UE4

I completely agree about SSR, that is already problematic without VR since reflections suddenly disappear on the edge of the screen, but in VR that looks even more wrong. And it’s quite expensive, a lot more than SSAO. I tried to use SSR in VR for a while, but it just doesn’t work.
