workflow question July 2, 2026, 12:48 a.m.

The rop has a parameter for 'files to save' that lets you control exactly which layers are saved. It probably doesn't save any cooking time, but will save I/O time and prevent file updates to files you don't want to change.
Nice,thanks! I will check it out.... my issue is that i am sending the scene to a renderfarm which means is more efficient to prerender the usd stage file before rendering, but if everytime I do a test the stage needs to take 9 min to save the usd it kinds of crap.

Definitely making the animated rbd an object will be better.

EDIT: yep it was the "files to save" what i needed to set up thanks!

workflow question June 30, 2026, 9:05 p.m.

Hi a silly question I think. How someone manages what the usd overwrites on a final stage usd?
Basically I have an animated geometry and then we have a camera and lights on the scene.... it feels to me that is overkill that every time I hit save to disk on the usd rop it saves everything, even if I am just tweaking cam parameters.
Is there a way to manage this?
Basically to have the animated geo on a separate usd or layer?
Honest workflow question here, will like to know best practice.

Seems a 590 driver bug.
A short-term workaround seems to be to set this envvar
KARMA_XPU_OPTIX_FORCE_OPTIXIR=1

Thanks will give it a try soon enough. A bit busy in another project now, But will definitely come up soon enough.
