Applying Animation Modifier to Animation on with Virtual Bones crashes Editor

Development Character & Animation

I’ve created an Animation Modifier that reads curves in an animation in order to generate foot sync markers. If the Animation Modifier is applied to an animation on a that has virtual bones the Editor will crash. If you remove the virtual bone(s) and re-apply the Animation Modifier, it will run correctly without crashing. Add the virtual bone back and re-apply and the editor will crash.

To Reproduce

  1. Open animation and re-apply Animation Modifier - no crash
  2. Open and add a virtual bone
  3. go back to animation and re-apply Animation Modifier - Editor will now crash

Hey EightyGee,

I’m no longer seeing this crash in 4.16.2. Can you check that it still occurs?

I’m doing this:

  1. Open animation
  2. Hit “Apply All Modifiers” in the “Animation Data Modifiers” tab
  3. Add VB to the left foot bone
  4. Hit “Apply All Modifiers” again.

Let me know if that’s incorrect.
