Title says it all. I love the Bhclassic format, use it all the time to go back and forth between Houdini Touch (then to any other 3D software). It’s great, it holds meshes, geometry, lines, points, groups, point attributes, everything… currently I’m running sop.save() in a text python command, but I think it’s a little slow, and I have not figured out how to multithread it, but if this could be added to the flydown list of FileOutPOP that would be handy.
