When working with big scenes, it is nice to only load in what you want to see.

I know about the visibility drop-down on the Scene Graph Tree. Checking off the “Load Payloads” and then manually loading the ones I am interested in does exactly what I need, however for some automated workloads I would like to turn this off and then choose which payloads get loaded via code. Any ideas?

Have a look at the hou.LopViewportLoadMasks object returned by hou.LopNetwork.viewportLoadMasks. Everything that you can do in the scene graph tree can also be done with those HOM classes.

Thanks. This looks exactly like what I was searching for.
