180 degree Smart Bone "snaps" back to beginning

[JoelMayer]

Hi there!

I have a weird problem. I'm working on a Headturn for my character and made a 0-180 degree SmartBone for that. Now, whenever i manipulate the bone and get to the 180 degree angle, it snaps back to 0 instantly. It doesn't seem to do that when i hold down the alt-key but switching the ignore IK chain option on in the bone menu makes it not react at all to anything...

Any ideas what the problem might be?



Thanks!

Does it work if you rotate it less than 180 degrees?
I may need to see a file with just the skeleton.

Thanks for your help!

You can find the file here:

No, it doesn't do that if i don't rotate all the way to 180...

Wow, that's a really weird and specific bug.

Apparently if you only have one, unparented smart bone, this can happen. Adding another unparented bone fixes it.
The transform bones tool work correctly either way. It's just a problem for the manipulate bone tool.

Thanks for your help! I'll try that and i guess i'll make an additional Bug Report Post then...
