In the ‘material libray’ node, there is a parameter called ‘Tab Menu Mask’. It seems to define what kind of nodes can be displayed in the menu. I ended the name of my node with ‘builder’, and it successfully appeared in the menu.

Regarding ‘nodeFlag’, I use Python in ‘OnCreate’ to control it.

This may not be the best solution, but it has indeed solved some problems.

I still haven’t solved this problem.
Finally, I decided to manually import the bgeo cache into the lens using sop_import. Or cancel this option for smaller data. The reason I found this problem is that in the case of particles, artists may trigger situations such as deletion outside the viewport.
As long as I don’t output USDA files, it can still work.

I am using this setting for USDA output. However, the visibility attribute loses some time samples depending on whether the ‘Flush Data After Each Frame’ option is used, causing the model to disappear. Did I miss any steps? Thank you very much for your help。
