In the Solaris LOPs stage context, in the Scene Graph Tree, when you right-mouse on a material, there is a menu item called Select All Bound Geometry.
I would like to be able to do this via python. i.e. return a list of all the USD.prims that are bound to this material. So that I can programmatically make modifications.

I checked here, but couldn't find any reference to this function:

Thanks

On that page, look for the example of using a hou.LopSelectionRule (search for `setPathPattern`). Then just change the setPathPattern call to `ls.setPathPattern('%geofrommat:/materials/iaTank_BrassMaterial')` (see https://www.sidefx.com/docs/houdini19.0/solaris/pattern.html [www.sidefx.com] for more information on specifying patterns).

I don't know if syntheticperson's question was more in the line of, "what is the python equivalent that computes %geofrommat/select all bound geometry?" For %matfromgeo we can use , but I am failing to find anything that could do the %geofrommat.

Does anyone know a python func that could do that?

The method you suggested, when working with a bit more complex scripts will quickly run into the following warning "Read lock failed because of existing lock: ... This may cause performance issues, and should be avoided if possible", which I am not too sure what it actually means and its implications.
