Question Issues using HumanPoseHandler to manually set muscle poses.

I'm having an issue trying to manually set muscle poses in Unity. I downloaded a project from Gitub
https://github.com/umiyuki/HumanoidHandPoseHelper to get a reference on how to achieve what I need as I am not to familiar with Animation/Avatar API's. When trying to use the tool linked my character just disapears when the script is activated, I am trying to figure out why this is. Saving the clips in the tool works but any visualization does not. I'm almost thinking its broken due too differences in Unity versions as the project was made quite a while ago, although I am not seeing any code marked as Depreciated in my IDE. Any one have any ideas what might be going on?

Side note while messing with it I tried changing my models import settings and when I turn of StripBones on the importer my character disappears in the exact same way.

 

Just wanted to thank you for this script, this was exactly what I was looking for and I was able to get it to work during gameplay as well. I added an extra variable so I could use a slider to open both hands. The key was to add an update during LateUpdate after any animations might have been applied.

I'm having problems with it working properly with only 1 hand the other one crunches up improperly. I'll update here if I get it figured out.

 

So this may be related to your issue. I tried dropping in a new character into my scene and adding the hand pose script. The character immediately darted off screen. It seems to be related to the bodyPosition vector, which is non-zero for some reason. I changed this line and the character stays in place.

Code (CSharp):

1.         pose.bodyPosition = Vector3.zero;
2.         handler.SetHumanPose(ref pose); //??????
