Rotation keys in world

MightyAz

Hi there.

I haven't seen this answered on the forums.

Just wanting to verify bone rotation behaviour. Are rotation keys offset relative to a bones current rotational value at all times?

I just noticed that offsetting any bones rotations in setup mode will affect any existing animation on that bone by the same offset. I haven't seen this is any other animation package I've worked in. Normally I would make adjustments to the animation, or create a parent node to correct.

I animate rotating a bone 0 - 20 degrees, then I expect that value to remain 0-20. In Spine, if I rotate the bone 20 degrees in setup mode it becomes 20-40 in the animation.

Is this expected?

Yes, it is expected. Keys in Spine are relative to the setup pose. There are situations where this is very useful, and others where it's undesirable. If the setup pose had no influence on animations, it would be less powerful. The setup pose would be equivalent to the pose of a single frame animation. If you do want a different setup pose or the equivalent of multiple setup poses, but you don't want to change your setup pose because it would wreck your animations, you can use an animation with a single frame for the pose you want. You can mix to/from that at runtime as you wish.

That solution would end up being pretty circular. Any change to the skeleton again, would still affect the one frame animation.

If there was a function that I could choose, to "offset this change in all animations" I agree it would be very powerful, but right now it feels a little obstructive and quite fragile.

I can work with it.

You can use the Adjust tool to offset all selected keys in an animation.

As Shiu mentioned, Adjust may help somewhat. You can use this issue to track a "setup mode compensation" feature request:

Thanks guys.

Adjust tool is a nice workaround for now.
