Difference in contrast of Karma viewport and render May 17, 2024, 4:38 p.m.

The Karma viewport always appears darker than the render, even when using the same render and OCIO settings.

Here is the Karma viewport:


And here is the Karma render:


I attached an example file.

Why do these not match?

Yes, if I set that variable, the issue goes away. This is with version 20.0.688.

System specs:

Core I9 14900K
128 gb ram
single RTX 4090 studio driver 552.22

I have had a similar issue with packed primitives, that unpacking fixed. With this file, the geo is not packed. Subdividing the geo will change where the artifacts occur, but they will still show on a few frames.

I keep running into this issue on multiple projects, and have no idea what is causing it. Whenever I render to Mplay or to disk I end up getting artifacts randomly on fast moving geometry. They appear like blocks of missing motion blur like in the image below.



The above image is the scene view from the stage, and below is rendered to Mplay. Sometimes the artifacts will appear in the scene view as well, sometimes not.

Has anybody ran into this? Any idea how to fix it?
