Hi Maarten,

thank you very much for sharing your feature request. I really appreciate that.

I think that would be a great usability improvement and I've added this idea to my "ideas for the future" list. I use this list to prioritize new features for upcoming updates.

"ps. Not sure if I should put this in Questions or Ideas...?"

No worries, I moved it to the "ideas" forum.

Best regards,
Peter

Hi Sean,

thank you very much for your support request.

When you convert your animation from FK to IK, UMotion has to re-sample your animation. That means that it has to goe through the animation frame by frame. If the pose on the current frame and on the previous frame is different, it has to create keys at the current frame. In your case, the animation curves might introduce changes between your placed key frames so in order to match that movement as close as possible, UMotion is going to create keys at these in-between places too.

You can delete the newly introduced keys manually (tip: keep the FK keys so that you know where the original keys have been), but you might need to play with the animation curves of your new key frames to match the original FK animation. Setting the display option of the "Rig Layer" to "Both" is going to show you the bones of the FK layer and the IK layer at the same time, making it easy to compare your IK animation with the original FK animation.

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 need to either manually create key frames for your changes (select the bones you want to key, then click on "Key Selected" --> "Key Modified" e.g.) or you should set "Auto Key" to "Generate" to automatically create keys whenever you adjust your characters pose.

The quick start tutorial covers both methods:

Hi Sean,

thank you very much for your support request.

This restriction was implemented because there are some edge cases where a one key frame animation doesn't work as intended. I recommend that you select the master key frame (click on the top-most key to select all keys on that frame) then use CTRL+C, move the frame cursor one frame forward and then press CTRL+V. Thus creating a two frame long animation with no motion.

If I'm not mistaken, this shouldn't increase the build file size of the *.anim as curves with only two key frames are optimized into a "constant" curve by Unity. You can see the build file size in the Inspector of your *.anim. Please note that the size the *.anim has on your disk (shown in Explorer/Finder) is NOT the size it consumes in your built game.

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

Hi RadiumLHY,

thank you very much for your support request. I've translated your question to English (please post in English in the future).

The IK features are only available within UMotion. Once you export your animation the affect of the IK constraints is baked into the animation. You can export your animation as *.anim (only compatible with Unity) or *.FBX (compatible with most 3D modeling applications). When exporting to *.FBX, I recommend exporting the animation into the *.FBX file of your character (set "Write Mode" to "Update Existing" in the export settings).

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

Hi,
thank you very much for your support request.

Moving the local position of human bones is not supported (and is probably not what you are looking for, as real life humans are not moving the local position of there bones as that would mean that the bone moves out of the joint). I think what you are looking for is Inverse Kinematics. The quick start tutorial shows you how to quickly setup and use IK:

Hi,
thank you very much for your support request.

A UMotion project is per character. So if you want to animate a new character, please create a new UMotion project for it.

"Furthermore, is it possible to delete or hide the properties I'm not using in the dopesheet view?"

Yes, you can do this via Config Mode. When you select a bone/transform, you can set it's Visibility to "Lock". That is going to hide it in the Scene View and in the Clip Editor. You can also hide only certain properties of a bone (position/rotation/scale) via the "Properities" drop-down field:

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

Hi,

thank you very much for your support request.

Sure, by using a Custom Property Constraint in "Component Property" mode you can animate any property (e.g. the Renderer.enable or the GameObject.active). You can assign the Custom Property Constraint to any bone/transform you like (it doesn't necessarily have to be the one you want to control with the constraint).

For further information, please check the manual at "Pose Editor/Constraint System/Custom Property Constraint".

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

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

The FK to IK conversion is "lossy" by it's nature (because IK has less degrees of freedom than FK). By comparing the before/after pose from your video it looks like the algorithm is only off by a few degrees (at least that's how it looks on the video to me, let me know if I've overseen something). Assuming that you convert your animation to IK because you want to modify it anyways, this small imperfection are usually acceptable.

If you need to further improve the animation, add a duplicated version of your character to Unity Timeline with the original animation attached. Then use the "Sync" button to synchronize UMotion with Unity Timeline. That way you can preview both animations at the same time (overlaying each other, toggle visibility of the Timeline assigned character) so you can manually do some adjustments where needed.

Please let me know in case you have any further questions.

Best regards,
Peter
