Hello,

Any clue what's going one here ? (see attach) I havn't done anything that crazy with the render settings.

I'm going to guess that this is a stitched image and not rendered with the spherical camera?

Hi bigben,

No, no stichting here, it's a direct terragen output, using spherical cam.

Wow. Haven't seen that before. Have you tried it with terrain. It doesn't appear to be affecting the sky, only the clouds, but vertical lines evenly spaced at 24° is pretty unusual. Is the cloud using a single node for the density?

I've seen this problem occasionally in some other renders (not just spherical renders), and I think it's the GI. You might need to tweak the GI cache detail and/or the GI blur radius. What are they set to now?

Hi Matt and bigben,

There is a terrain in the scene (basically the default scene one, I just lowered the displace elevation).

Hi Matt,

Thanks a lot for the help.
GI blur radius was on 3 ... a value of 6 resolve the problem !
