jit.gl.bfg scenegraph has no owner
Looking like jit.gl.scenegraph disappeared a long time ago - (I only go backwards to 8.6.5)
So why this error?

typically means the gl object can't find a valid context. happy to look at a full patch to try and reproduce if you feel this is in error.
I agree this error message is quite cryptic. There is no jit.gl.scenegraph object (never has been), this is an internal object owned by a context like jit.world or jit.gl.node.
Hi Rob
Here is simple set up that gets error
...when turning world on after turning off the first time
also
release notes from Max 8.0.4 (I assumed jit.gl.screnegraph was an object)

I can't reproduce any errors with your patch unfortunately.
(apologies for the confusion in the release notes)
No error in Max 8, only in 9
ok toggling context visibility was the missing step. I can reproduce and will investigate. It looks like everything remains functional and the error is harmless, correct?
Yes everything works ok. Just looks bad if students im tutoring turn in patch with strange error
Thanks for taking time to investigate
Following, as I also got a few patches throwing this error since 9.0.4 I think (and couldn't manage to isolate it). Harmless for me too.
Thanks for the info. This will be gone in the next release.
Following also got a few of these. :)
