I'm new to Houdini so i'm sure it's an easy solution. If I have a polygonal object (geo node with sphere with primitive type set to polygon) and set the viewer to show flat shaded or flat shaded wireframe the object becomes invisible. Yet if I set it to smooth shaded it's visible.

I thought it might have been something I changed in the settings so I deleted the Houdini folder in my documents yet the issue is still there. I then re installed and still didn't fix it.

Which build are you using?
May be a bug!

You were correct, thank you!

I wasn't aware that I had to manually update the software so I had been using version 13.0.331.
