Hi,

thank you very much for your support request.

Doing an "aim" inside an animation means that it is baked into the animation and won't adapt at the target's position at real time. That's why usually a real-time IK solution is used for this (on top of the regular animations) which calculates the pose at real time based on the current target position. This for example is final IK's aiming solution:

Link: Final IK - Asset Store

If you have a special case where you want to bake the result into an animation clip (because you're targets don't change at realtime) you can extend UMotion's functionality by (e.g. Final IK's Aiming solution) using the UMotion callback mechanism. That way you can preview and key the behavior inside UMotion. For more information regarding the UMotion callback mechanism and how to use it with Final IK, please check out the UMotion manual at ("Pose Editor / Options" headline "Extending UMotion").

Don't hesitate to contact me in case you have any follow-up questions.

Hi Woodyy,

thank you very much for your support request.

Ok so the face rig is using blend shapes for the facial expression or is it using bones? Are you sure this isn't a problem with your character / your import pipeline? You can verify if the blend shapes on your character are working by dragging your character to the Unity scene. Then look for the GameObject that has the SkinnedMeshRenderer component and open the "Blend Shapes" foldout in the inspector. Here you can play with the blend shape weights (100 means full influence of the blend shape):

If the blend shapes also don't work in that case, you might want to double check your setup in blender and your import/export settings. If they do work using the method mentioned above, it might be a problem with UMotion not previewing the blend shapes correctly for some reason. If that is the case, I would love to take a look at it. Please send me your character (without textures if you want) and your UMotion project file via email support form (or request a link to my dropbox if file size is too big for email transmission).

Please let me know if you need any further assistance. I'm happy to help.

Best regards,
Peter

With UMotion V1.26 I introduced an easier way to update a custom transform to a real transform:
Create new empty GameObjects in your character's hierarhcy (outside of UMotion) that are named like the custom transform inside UMotion and are located at the same position in the hierarchy.

When you then assign the character to the pose editor, UMotion is automatically going to ask you if it should convert the custom transform definitions to real transform. All other steps mentioned in my previous post are not necessary anymore in this case.

The animation data for those transforms is then automatically included in the exported animation.

UMotion V1.26 is shipping in the next one or two days via the asset store.

Please let me know in case you have any questions.

Hi Antoine,

thank you very much for your support request.

Let's narrow down the cause of this issue:

1. Select one of the exported animations (that you use in Timeline and that jitters) in Unity's project window. In the inspector preview section at the bottom, play the animation. Does it also jitter in the preview window?
   
2. You can also try to drag & drop the character you use in Timeline from Unity's scene into the preview window. This is going to preview the animation using the correct character. Does the jitter appear in that case?
3. If the problem is not present in point 1 or point 2, does it happen if you scrub through the Unity timeline (when not being in play mode)?

Please let me know the results of your investigations, so that I can further assist you.

Best regards,
Peter

Hi,

thank you very much for your support request.

When dropping the Gameobject into the pose editor I get the 'Hips' already defined.

That happens when you drop a humanoid character into a UMotion project initially created for a different humanoid character. A separate UMotion project has to be used for each of your characters. If you're character is of type humanoid and you want to use/edit a humanoid animation you created for a different humanoid character, just export said humanoid animation from the UMotion project A and import it in UMotion project B (with the correct characters assigned to the pose editor respectively).

For IK rigging, you can use the IK Setup Wizard in UMotion. It automatically creates IK chains for the legs and arms. Unless you're doing something like a "playing the piano" animation where precise finger movement is very important, I would recommend not to use IK for the fingers. It's usually easier to just use the finger sliders in the muscle tool assistant. Another trick is to select each finger bone, then use the rotation tool which will equally apply the rotation on all finger bones at once making it bend nicely.

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

Hi,

thank you very much for your support request.

When working with humanoid, I highly recommend setting "Write Mode" to "Update Existing File" (in the UMotion export settings). Then select the fbx file of the character that you have assigned to the pose editor as destination file. When you now export, your animation is written into the FBX file of your character. Meaning that it is imported with all the correct settings automatically.

For more information, please check out the manual (click on the question mark button in the export settings to open the corresponding manual page).

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

Hi Scott,

thank you very much for your feedback.

I'm sorry to hear that you are having such a hard time working with UMotion and Unity Timeline.

When you want to modify a timeline animation, you need to make sure that you export into the correct directory so that the animation that is used in Unity Timeline is updated/overwritten. If you select an animation clip in your Unity Timeline and then click on the animation clip field shown in the Inspector window (and if you have Unity's project window opened), Unity is going to highlight you the file in your project window.

Then open UMotion and make sure that in the export settings, the export directory points to the exact same directory. In order to avoid confusions, I also recommend that you use unique names for your animation clips throughout your whole Unity project.

If the export directory is not correctly setup in your UMotion project, UMotion is going to export the animation to a different location in your project. Unity Timeline is then still using the old animation.

In addition, the animation clip which was modified with a weapon does not work on the original character which has not the weapon because of rig differences.

Humanoid animations are rig independent (due to animation re-targeting). So if you create a humanoid animation for humanoid character A, it can be played on humanoid character B as well. But please note that none humanoid bones (e.g. additional weapon bones) might not translate well between characters because re-targeting only works on humanoid bones.

If you just want to edit an animation of your character with the weapon, you should be able to directly work on that character (and his weapon) within UMotion. There should be no need to remove the weapon before working with UMotion. What problem did let you think that this is necessary?

I hope this sheds some light into your situations. If you have any further questions, please let me know.

Best regards,

Peter

Hi Elsiehar,

thank you very much for your support request.

Yes this is expected, that's how IK works. The IK rig (the blue bones) are controlled solely by the IK algorithm. This algorithm automatically adjusts the rotations of the individual leg bones in such a way, that they reach the IK handle of the corresponding foot. So if you select the IK handle (this is the wired cube at the ankle) and move it with the move tool, your legs are going to bend/rotate so that they end up at the IK handles position (FK/IK Blend needs to be at 1). By moving the pole target, you can define where the knee is pointing to.

The FK rig on the other hand gives you full control by allowing you to rotate every bone manually with the rotation tool. As you might already think, both methods have their advantages that's why the FK/IK Blend control exists which allows you to switch between them (even during an animation) so that you can use the best fitting solution for your animation scenario.

I recommend that you play around by moving the IK hande/pole handle so that you get the hang of how things behave. Btw. rotating the IK handle is going to rotate the foot bone.
