Hello,
My team is encountering very high memory usage with the USD Composer app template whilst rendering frames for an extended period of time via Movie Capture.
Here is a log file showing the RAM usage of the Kit process over time:

As you can see, after 13 hours of rendering, Kit has single-handedly filled the RAM, at which point Windows probably started killing random processes. This is not ideal, we’d very much like the ability to render overnight.
System specs:
Windows 10 Enterprise
i9-14900K
RTX 4090
64GB RAM
We’ve encountered the issue with the USD Composer app template with Kit 106.4 but as far as we can tell, it also happened with versions as far back as 106.2, so not a new bug with the latest releases.
Kind regards
