Hi all:

Every time I start a new interactive render from the Render View, even if it's a brand-new scene with nothing else except a new Mantra node dropped into it, I keep getting this warning message popping up in the console when I start a new interactive render:

Unknown operator type: Vop/global

Even re-creating my preferences didn't alleviate this issue. While afaik it doesn't seem to have any impact on the actual functionality, I'm wondering if this is normal behaviour for anyone else?

Thanks!

I am getting similar errors with one of my scenes, just a little bit different:

“Unknown operator type: Sop/null”
“Unknown operator type: Sop/attribvop”

No idea so far what causes them.

Not just for this issue, but in general terms, if you see an error message that doesn't make sense to you, please log a bug. Thanks!

Did you happen to a new Operator Type and then move on? I placed a python print statement in the onCreate event of a default operator I created and now it shows up in the console every time I open Houdini. (which is expected operation)

Not that I know of.
But I copied everything over to a new project and now the error is gone.

If I get this again I'll send a bug report.

I got this error again and filed a bug report. I am posting Support's answer here in case someone else gets the same error messages:

This is because the .hip file contains an entry in OPpreferences for Shop/vopmaterial which is not an HDA

To see that, open Window > Hscript Textport and do ‘otprefer’.

To clear the error from the scene do ‘otprefer -c’. See ‘help otprefer’ for more info.

This indeed got rid of the error, although I am still not quite sure what I did to cause it.
