It's not a bug. It's because the polys have a Cd attribute of 0,0,0 (black). They're also imported as a bezier nurbs.

You need a color sop to change to white (normal Houdini poly colour) and a convert sop to change to polys. You can adjust the resolution on the convert sop or use a resample before the convert to adjust the res.

@peteski: This isn't working for me in 18.5.351. I select multiple nodes and the Make Selection box comes up, but when I select the node type and hit Accept, nothing happens in the Parameter panel. Any ideas?
