Strange Atmosphere from Orbit

[PeanutMocha]

I'm rendering a planet from orbit using 2.2 (can't use 2.3 due to a specific bug that affects my scene).  When I'm fairly close in (upper stratosphere type distance) all looks great, but from mid-orbit there are strange artifacts.  Any idea how to fix that in 2.2?  The atmosphere renders cleanly in 2.3.

Are you sure it's the atmosphere? Have you disabled atmosphere and tested the same camera position? If it is the atmosphere, do you have Sample Jitter at anything other than 1 in the Atmosphere node Quality tab? How many samples are you using for Atmosphere? Are you using Raytrace Atmosphere, if not try enabling it.

The render looks normal when I disable the atmosphere..  Sample Jitter is 1, Atmosphere samples are 32 (adjusted up from 16, same result) and Adjust to distance is checked.  Raytrace atmosphere is enabled.

Some of my closer-in frames are now showing this kind of artifact, though much less apparent (image attached).

What happens if you switch off GI?
(to do this: disable enviro light and set GI relative detail and sample quality both to 0)

I found a similar tiling effect on a final render in one of my scenes - it turned out that if I disabled acceleration on the cloud layers, it resolved the problem...

[PeanutMocha]

Not using the Acceleration Cache seems to have done the trick!

Have to retract... other altitudes manifested the same problem.

[Tangled-Universe]

Ah that's great to hear and good you reported it back here

Oops...didn't work...

Yes, like Oshyan and I said: try disabling GI

[Oshyan]

So does it still occur when you disable all cloud layers? How about disabling GI?

[PeanutMocha]

If I disable the cloud layers the render is fine.  Turning GI relative detail, GI sample quality and GI blur radius to 1 does not fix things.  Is that what you meant?

[Tangled-Universe]

No, scroll back to my first reply

[Oshyan]

Ok, so it sounds like a cloud rendering issue. What are your cloud samples? It happens even if you turn Acceleration Cache to none? Would it be possible for you to share the TGD (you can do so privately if you prefer by sending it to our support email address).
