Post this on the Redshift forum, they'll help you out.

I don't think you can, since it's not represented as nodes in USD unlike MtlX

I'm new to Houdini in general and Python too.
When people make their own material managers how do they save selected nodes on a disk and then load it?
I was just experimenting with Houdini couple of days ago and tried to save some pretty complex material nodes with asCode() python function, but the generated code was enormous in size.
Is this the only way? Or correct way? I know this is off-topic and sorry

How to load generated "save vex code to file" back to material library network?
Is there a python way? I couldn't find any info.

So I was flattening out the stage when I was exporting via USD ROP, that was the culprit.

I made a simple scene with an animated camera then exported it with the USD ROP.

I use this command with hcmd.exe to render out 48 frames.
husk -f 1 -n 48 --renderer Redshift "C:\rs_test.usd"

It only renders one frame and then stops. Any ideas?
