Right to the point: My AO has vanishing issues near the corner of my screen and (less importantly) 'speckled' shadows, but it's much easier just to show you with a 6 second youtube video. - Look at objects on right for vanishing and the grassy floor for speckle (assuming YouTube compression lets you see the speckle lol).

And here's my AO settings at the moment. I've tried messing with just about every option and I can't seem to fix this.

This is my first time trying creating an ENB. Be gentle.

Very big sampling range with very low sampling precision.

I thought the exact same when I noticed this issue, but with "very high" precision and really any amount of sampling range the issue barely changes.

[s]EDIT: The author(s) of Vivid Weathers allow the free use of their Skyrim 305 ENB, and using those SSAO settings works near perfect.
I'm just going to reverse-engineer the working settings : D[/s]

EDIT 2: Actually, the issue is still very much there. Theirs just wasn't dark enough to notice at first

SSAO is screen space technique, so it can't get data from outside of the screen and this is noticable as soon as you increase sampling range. It's the fact you can't avoid. Using huge values of AOAmount isn't good too, change mixing type if you want a lot of effect.

I had a feeling that's what it was, but due to the whole 'this is my first time' thing I didn't want to put my instincts particularly high on the trust list.
-Also I can't exactly find any helpful documentation on the enbseries settings, so I unfortunately have to bother real people about it.

Thanks for the quick responses! : D

It's okay, i prefer to answer questions instead of writing docs
