For some reason, the Maya 2011 undo queue periodically gets filled up with dozens of “refreshDynRelEdSelection” commands, making it a huge pain in the neck to undo stuff.

I’m seeing it right now in a file I’m working on.  The Dynamic Relationships window isn’t even open (though I do have nParticles and a fluid in my scene).

Has anyone else seen this?  Is there a way of preventing these commands from going to the undo queue?

Did you ever work this problem out? I started having this same issue. It’s driving me nuts.

I never did.  Please post your observations, if you’re able to narrow it down to a particular set of circumstances.  Although it’s definitely a dynamic relationship related function, it doesn’t seem to matter whether you’ve got the dyn rel ed open or not.  My guess is maybe it’s a script job that’s getting auto-installed somewhere?

One would think there’d be a way to flag a script or function to not report to the Undo queue.  Maybe it’s as simple as hacking the function to suspend and then un-suspend Undo while it runs.

The facility I’m currently at apparently has no support contract.  So if anyone out there is seeing this same issue & has access to support - please post in this thread if you’re able to get any updates from Autodesk on this.

That sounds to me like the scriptJob that updates the Dynamic Relationship Editor when the selection changes is still running even though you closed the editor.

Try this:

scriptJob -kill $gDynRelEditorPaneScriptJob;

THNKR: Thanks, that seems to do the trick.

Meotech: Does that work for you too? All I can add is that the first time it happened to me I was running a few dynamics sims. Specifically a soft body collision event. It happened to me again though in a brand new scene with nothing dynamic in it. Just a few skeletons, some instances and constraints. This is what kind of confused me. Anyway, running the command THNKR posted seemed to work for me. Hope it does for you as well.

Thanks for the suggestion!  I’ll put it on a button on my shelf to try out the next time it happens.

Just an update on this issue:  On the install of Maya 2011 (linux) that I’m currently using, the “kill scriptJob” solution seems to break the dynamic relationship editor.  So my workflow is:  open maya, work until undo becomes unusable, kill scriptjob, work until I need the dynRelEd again, quit, restart, repeat.  Very frustrating.
