[1.9.00] IK Timelines not deleted

Pharan

When you delete an IK Constraint (item in the tree), the timeline stays in the dopesheet, and then causes a crash when you scrub.

0) Open Spineboy
1) Set up a new IK constraint. (make a new bone, select two bones, make a new constraint, target the new bone)
2) Set some keys in the timeline. (I set some keys, checking and unchecking the Bend checkbox. Not quite sure what this is for yet)
3) Play the animation (works fine. get some cheap laughs based on what you constrained.)
4) Delete the IK constraint. (the IK timeline will stay on the dopesheet)
5) Click anywhere on the editor timeline. - crash -

An unexpected error has occurred:

Thanks for the report Pharan, that of course needs to be fixed. Bend is used to determine which way the chain bends if the bones are stretched out fully.

Pharan

Thanks!

I also notice you can select two bones that don't have a direct parent-child relationship and pin those.
In this case, the animation seems to play okay, but scrubbing causes the pinning not to be applied.
I'm still not quite sure if it works as intended in this case (I actually don't have a frame of reference to tell if it is. I've never used IK anywhere else) :p.

(And I just noticed Spineboy has bone icons on his shoes.)

Søren

You're right something is amiss there. I've just notified Nate about it as well.

(And I just noticed Spineboy has bone icons on his shoes.)

Not sure what you mean with that ? 🙁

Pharan

Oh, no. I just meant that you drew bone icons as the actual design of spineboy's brown shoes. On the images.
It threw me off for a split second 'cause I thought they were actual bones. 😃

Søren

Ahh! 🙂 I had actually forgotten about that, well spotted!

The bugs you mentioned in this thread have now been fixed and we'll do a new build later.
