Just tried houdini19.5 on ubuntu 18.04 and found this problem.Everything shows correctly in Obj viewport,but just show nothing atfter imported into Solaris,and houdini even crashes sometimes.
Does anyone know how to fix it ?
Thanks!

In the viewport in the top right menus, first from the left, what did you check? Houdini GL or Karma or Storm?
You need to build a stage network with imported objects, lights cameras and render options. Show us what you got.

Yes, I encountered the same issue. Everything works fine at the OBJ level, but after switching to Solaris, I can't see anything in the viewport under Houdini GL mode. Only when I switch to rendering mode can I see the objects.

What version of H19.5 exactly? How are you bringing your geometry from /obj into /stage? Can you provide a hip file? Thanks!
