Hi Dave,
thank you very much for your input and also thanks for your nice words. I'm glad you enjoy working with UMotion.

The problem I see with this feature is when people new to UMotion accidentally use it and then get confused why the pose doesn't update while scrubbing. Maybe a different but similar affective feature would be copy/paste buttons in the pose editor. What do you think?

Best regards,
Peter

Hi Dave,
thank you very much for your support request.

IK pinning changes the coordinate system of your keys (from one local space to another local space). When looking at position/rotation curves, you see these jumps where it switches between different coordinate spaces.

Under the hood, IK pinning is just a simplified mode of the child-of constraint. You always need to keep in your head that changing the parenting affects your keys (existing keys need to be converted into the new coordinate space etc.). More information can be found in the related manual page (headline "Dealing with spaces") and in the following video tutorial:

Please let me know in case you have any follow-up questions.

Hi,
thank you very much for providing feedback. Much appreciated.

You can assign a custom shortcut to your preferred export option to avoid accidentally clicking the wrong option. Shortcuts can be assigned by clicking on "Edit --> Preferences" in the clip editor.

Best regards,

Hi Dave,

thank you very much for sharing your idea.

This is more or less already possible, but you need to work directly on the animation data (not via the humanoid format as humanoid always requires re-sampling on import/export which is introducing keys for each frame again).

1. Decide on a character you want to use to do your mocap clean-up.
2. Convert your mocap animation to generic (for that character):
   a) Configure your character and mocap anim as humanoid.
   b) Create a humanoid UMotion project for that character and import the animation.
   c) Export the animation into your character's *.FBX file.
   d) Configure your character as generic.
3. In the animation tab of your character's FBX settings you now have exactly those options you described in your idea.
   
   
4. Create a new UMotion project of type generic and edit your animation. You are now working directly on the animation data (due to the use of generic), no re-sampling required when importing or exporting the animation. Data-wise, this is equal to editing the mocap animation in motion builder, maya or similar.

With humanoid, you do not have the level of control over the animation's data that would be needed.

PS: Step 1 and 2 are not necessary if your mocap animations can already be used as generic because they where all exported using the same standard character model (by your mocap software).

Hope this makes sense to you. Please let me know in case you have any follow-up questions.

Best regards,
Peter

Hi,
thank you very much for your support request.

You guessed right, you need the child-of constraint to do that. With it you can make the right hand's IK target the parent of the left hand's IK target.

If you've setup your IK with the IK setup wizard, then your IK targets already use a child-of constraint (to offer the IK pinning capability). IK pinning is a special mode of the child-of constraint that allows you to toggle the parenting between two states only.

1. Go into config mode (pose editor) and select the IK handle of the left hand.
2. Open the constraints tab and scroll down to the child-of constraint.
3. Disable IK pinning mode.
4. Switch into pose mode.
5. In the clip editor, set the green frame cursor to frame 0.
6. Select the left hand's IK handle and in the channels view of the pose editor set the IK handle of the right hand as parent.
7. Click on Key Selected --> Key All (pose editor).

Result: If you move the right IK handle, the left should follow accordingly.

More information about the child-of constraint can be found in this video tutorial:

Hi,
thank you very much for your support request.

Deleting intermediate key frames is not intended to change the tangent mode of the adjacent keys. So if you have custom tangents for the keys left and right to the intermediate key you are deleting, these will be kept (which can result in a different curve overall).

In your screenshot, there seem to be some keys with custom tangents, some use linear mode,... those are kept and not automatically changed to "Clamped Auto" (which would generate a smooth transition). If you change all your keys to "Clamped Auto", deleting intermediate keys will result in the smooth curves you might be asking for.

Does that answer your question or do you still see a behaviour that doesn't fit into my explanation?

Best regards,
Peter

Thank you very much for your detailed description (in your answer below).

So if I understood you correctly, you primarily need this in order to copy IK handle's world space positions around. You can already do this:

1. Select the bone/transform of which you want to copy the world space position.
2. Select the move tool and set pivot to global.
3. Click on the menu button in the upper right corner of the move tool assistant and select "Copy Position".
   This copies the world space position.
   
   
   PS: Via the preferences menu of UMotion you can even assign a shortcut to this.
   
   
4. Move the frame cursor to the desired position and/or select the destination bone/transform and "Paste Position" (via the tool assistant menu again).

Limitation: Only works with one transform at a time (having multiple transforms selected copies the center position).

I can offer setting the world space position/rotation via the UMotion API in the future. I've put an entry on my "extending API" todo list.

Please let me know in case you have any follow-up questions.

Best regards,
Peter
