nHair - Make Curve dynamic Fatal Crash - Help!

[Anonymous]

Hi All

I'm following a tutorial on rigging a fish, and as part of that, the guy takes an iK curve and makes that curve dynamic in the nHair menu. When I do this, I get a fatal error. 

If I do this on a clean scene, it seems ok, but anything relating to this scene will crash. I can export the geo only and import into a fresh scene, and it crashes. This is a bit of a shop stopper, can anyone help? I've included a crash report.

Windows 10, Threadripper 3970x, 2080ti 128gb Ram, Maya 2020.1 (also tried on 2019)

Any help much appreciated

Best,

David

update - I tried this on my laptop, Dell XPS 15, just in case it was a hardware issue. Sadly the the same thing happened which somehow I find more concerning. 

attached log of crash on laptop....

Any suggestions for this would be greatly appreciated...

Hi @Anonymous 

Thanks for posting 🙂 I did some research and found that this is an issue that our development team is currently working on. Due to legal restrictions, we are unable to speculate on when that fix will be implemented into an update for Maya, but we can offer the following workarounds:

• Ensure that the Timeline is always on 1 or 0 when making curves dynamic.
• Ensure that viewport 2.0 is paused during the Make selected Curves Dynamic action.
• Set the evaluation mode to DG by navigating to Windows > Preferences > and click the Animation tab under Settings.

Thanks for taking the time to share your experience with us! And thanks for being a part of our community 🙂

Thank you Jordan, i'm impressed by the quick response - and also a response which doesn't include deleting prefs and re-installing! I really appreciate the fix, and indeed it did work! so thanks again! I kind of got it working 10 minutes ago (right before I saw the mail) in that the crash file actually made dynamic curves but it left me paranoid that further down the line something would unexpectedly die again. Hopefully I can continue and all is well.

All the best
