Very weird blur of sorts on LOD chunks. Using DH 2.0.0 RC3

Just noticed this, the effect is mostly visible on sand. Idk whether this is sand - exclusive šŸ˜„

Download the first picture to see the effect. Discord seems to limit the resolution, making it basically unnoticeable.

That's SSAO It's on every block Configurable in options

Still, the blur occurs in the edge of the blocks, if the blur is disabled theyre sharp as it should

Okay, this is really weird. First the terrain looked all blurred, then I teleported far away, then back and now it looks normal. Here take a look:

Hmm, Null might know more He did most of the SSAO stuff recently
ThunderBolt

tweaked as most as i could for reducing it, though is only a teeny bit :/

Here you can see it very clearly. Must be a bug?

I am using Rubidium and Oculus. Maybe they are the culprits?
ThunderBolt
ThunderBoltā€¢14mo ago

If you take a look at the last screenshot I sent, you will notice that both Noise and AO are present/enabled. Those are NOT two screenshots merged together, but one. It's just that DH terrain is in some (seemingly random) areas blurred and thus brighter. It's a bug, not a feature (as far as I understand, at least)
ThunderBolt

Im still confused how they even reached that observation logically
Steveplays
Steveplaysā€¢14mo ago
It's probably the lighting
ThunderBolt
ThunderBoltā€¢14mo ago
Do you want me to put on night vision plus the sun dead center above?
Steveplays
Steveplaysā€¢14mo ago
Sure, I really don't notice what you mean in my gameplay Not that I've been looking for that specifically though It could also be a lack of anti-aliasing
ThunderBolt
ThunderBoltā€¢14mo ago
Can you click the photos and see the sharpness in it?
Steveplays
Steveplaysā€¢14mo ago
oh at the top here?
ThunderBolt
ThunderBoltā€¢14mo ago
AO off

Steveplaysā€¢14mo ago
this?

and bottom right, it is really noticeable if you compare it with no AO
Steveplays
Steveplaysā€¢14mo ago
@Null Might know more, not sure what's going on here.
ThunderBolt
ThunderBoltā€¢14mo ago
so do you see that is blurry?
Steveplays
Steveplaysā€¢14mo ago
Yeah I do but I don't know why it's happening And I can't reproduce it on Nvidia
ThunderBolt
ThunderBoltā€¢14mo ago
Im on nvidia
Null
Nullā€¢14mo ago
ssao is intentionally blurred to hide dithering you can reduce blur radius and increase sample count
ThunderBolt
ThunderBoltā€¢14mo ago
I dont see any dithering without AO, in what situation should be noticeable?
Null
Nullā€¢14mo ago
ssao on, blur radius lowest setting
ThunderBolt
ThunderBoltā€¢14mo ago
ive set it to 1, i cant see any dithering. Edit, ok now i see it. Its barely noticeable, i do notice more the blur of the edges of the voxels. With 0 its absurd. So the problem with AO, its AO itself. Neat. Thx Null
Null
Nullā€¢14mo ago
So what's the issue specifically? Could you not find settings you liked? guessing it's either too grainy from dither, or too blurry?
ThunderBolt
ThunderBoltā€¢14mo ago
the issue is the blurriness. yes exacly ive found a middle ground after experimenting a little
Null
Nullā€¢14mo ago
did you try increasing the sample count? before I added the blur it was 128 should make dithering less noticeable at the cost of perf the dither and blur are so the samples could be dropped down, which over doubled perf on my end with DH
ThunderBolt
ThunderBoltā€¢14mo ago
so its that perfomance heavy
Null
Nullā€¢14mo ago
with 128 samples per-pixel, yes; but that's a lot
ThunderBolt
ThunderBoltā€¢14mo ago
whats your opinion on this?

Null
Nullā€¢14mo ago
here's 6 vs 32 samples; no blur

Nullā€¢14mo ago
looks good to me, but I'm less picky with grain/blur
ThunderBolt
ThunderBoltā€¢14mo ago
its still 6 samples 32 looks quite good
ThunderBolt
ThunderBoltā€¢14mo ago
@Denial VL Less blurriness.
