Issue with Karma CPU renderer.....black frames June 21, 2022, 7:13 p.m.

Any news on this? I am having the exact same issue with the .622 build.
Billowing smoke shelf tool renders every few frames black.
In the Karma viewport, rendering to Mplay and to disk, all the same.

Edit:

I think I found what this issue is related to. When I run a simulation with mem cache on and the render with Karma I get a black frame every now and then. However, if I turn off mem cache and render the sim directly (simming every frame at render time) then all is fine.
Tested in .589, .622 and .655.

H19 Karma no camera motion blur May 14, 2022, 4:02 p.m.

Just want to add this:
If you have a calculated rotation (like an expression based on $F) the Karma ROP viewport will not render motionblur for that rotation. If it is keyframed, it will.

shouldn't that be a light option, not a global view option?
