Hi,
thank you very much for your support request.

Ok so you've already exported your UMA character to *.FBX. That's perfect. Please make sure that the following steps are performed correctly:

Select the exported *.FBX and make sure that it is setup correctly --> Open the "Rig" tab in the Inspector and ensure that "Humanoid" is selected and that "Avatar Definition" is set to "Create From This Model". Click on "Configure..." and make sure that all bones are shown in green and the character is in a T-pose.

Now, drag & drop that *.FBX file into your scene. The created character instance should automatically have an animator component attached. Create a new UMotion project of type "humanoid" and assign the character to it. This should work without giving you a warning message.

The important part is that your character really is an instance of your exported *.FBX.

Please let me know if you need any further assistance.

Best regards,
Peter

Hi,
thank you very much for your support request.

You can animate finger bones just like any other bone. If you are using a "humanoid" character, you can even use the Muscle Groups Tool Assistant that offers some easy to use sliders for finger posing.

If you do not see the finger bones:

1) If you are using "humanoid", make sure that you have assigned the finger bones in the humanoid avatar configuration (select the character file, in the Inspector switch into the Rig Tab, click on "Configure...").

2) If you are using "generic" and you don't see finger bones, it's very likely that your character may not have separate finger bones. You can create some in a 3d modeling application.

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

Hi,
thank you very much for your support request.

I think what you are looking for is IK Pinning of the feet. When enabled, the feet stay at the same place even when moving the hips. When IK Pinning is disabled, the feet are moving with the hips.

When using the IK Setup Wizard, IK Pinning is automatically setup for you. For completeness, here are the related video tutorials:

Hi,
thank you very much for your support request.

Everything that is placed as a child of an Animator controller can be addressed by that controller. You can use animation clips that point to transforms that are not always available (but are added during runtime).

So while creating the animation (during edit time), place the weapon as a child of the hand. During runtime, use transform.SetParent() to make the gun a child of your hand.

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

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

The easiest way to setup IK pinning is by using the IK Setup Wizard. It automatically configures feet and hand IK targets to include the IK pinning functionality. You can convert existing animations to IK by clicking on "Edit --> FK to IK Convertion".

Here are some in depth tutorials (in the manual there is a nice overview of all available video tutorials in the "Video Tutorials" chapter):

How to use the IK Setup Wizard (and the manual setup approach).

IK Pinning uses the Child-Of constraint under the hood. Watch this before the IK Pinning tutorial.

IK Pinning.

And here a video tutorial where I use all of this in a practical example (fixing a broken MoCap animation):

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

Thanks for sending me the repo project. I have been able to identify the issue: When the left tangent mode of the first key or the right tangent mode of the last key is set to "weighte", the exported animation curve won't be played by unity. I've implemented a fix in UMotion V1.20p08 (should arrive on the asset store in the next few days).

There is an easy workaround you can apply:

1) Select all keys in your animation (in UMotion)

2) Right click --> Both Tangents --> Weighted

3) Do the same again: Right click --> Both Tangents --> Weighted

4) Export your animation

Thank you very much for reporting this issue.

Hi,
thank you very much for your support request.

Please make sure to measure the animation size correctly. The size an *.anim file has on your PC's disk is NOT the size the animation has in your game. It contains editor only animation curves that are generated by Unity for it's animation window (but are stripped in the build of your game). The build size of an animation is shown in the Inspector of the *.anim file:

Importing/exporting a humanoid animation file requires that UMotion re-samples the animation which can increase the animation file (it depends on the animation, but this should be definitely far below a factor of 9 as you've mentioned).

If the resulting file size is too high, export to *.FBX. This allows you to let Unity compress your animation (tune the compression settings in the Inspector --> Animation tab of the *.FBX file). UMotion's export to *.ANIM doesn't apply animation compression (it only removes duplicate keys).

Attention: When exporting a humanoid animation to *.FBX, always set "Write Mode" to "Update Existing File" to export your animation into your character's *.FBX file! This ensures that the humanoid avatar is correctly setup by Unity.

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

Best regards,
Peter
