I saw this error in the viewport yesterday and wasn't sure if this was a serious error or not.

Or am I doing too much OT? :roll:

I think you have been found out. You must move quickly before the Sith lords locate you!

Jedi is the library that glues the viewport to the rest of Houdini, handling node updates, lights, materials, and cameras (without JEDI, the viewport is basically gplay). It's pretty hard to tell if it's serious or not, without knowing the exact error.
