random SSAO flaw

[robcat2075]

Strange blotches appear on occasional random frames of an SSAO render...

 

 

If I render the same frame number plus 0.01 the mark will not appear...

Can you upload a sample project where this happens, Robert?

I just tried making a stripped-down version with only the brick wall... but that didn't produce the gash when I rendered.

So there must be some point between all-the-of-other-objects and none-of-the-other-objects that creates the problem.

I'll have to investigate further and report back.

Thanks, none-the-less, David!

Starting with the full chor plus a few additions, the gash is till there...

 

But if I delete all the aliens, (there are about 9 offscreen to the right) the gash is gone, with a new, smaller scratch on the front-most cushion...

Here's a birdseye view of the chor. The alien in the camera view is highlighted, the offscreen aliens are to the right of the camera.

 

But now I've gone through deleting each alien one-by-one,  re-rendering that frame and the gash is still there...

Have you tried making a new Chor?  I've had a few Chors get corrupted somehow...once I recreated them, things straightened out.  Also doing a reset has helped occasionally.  Your SSAO settings could also be the culprit.

These have been my go-to settings lately.

 

Hope something in there helps.

Thanks, David!

I'm finding out now that this must be a 19.5 problem. If I go render in v19.0 the frames come out properly.

I should have thought of this before since i already had a 19.5 problem with the regular color render of this scene.
