Rigged model - scaling problem

Hi guys,

I rigged some models, but didn't match their scaling. :/ They are all rigged to a human skeleton with the same bone count and their pivots are positioned correctly in 0/0/0.

They are controlled by the same kinect tracking data in Unity.
I scaled and positioned the models so that they match.
But during runtime the smaller models seem to have a Y+ offset.

There should be a light offset between the models, but why this big Y offset?
Any hints appreciated

 

Maybe because they are all at different scales?

Did you freeze the transforms (reset scale value) reset Xform before exporting out of 3D?

Is the offset a scale offset or transform offset? If the offset is only a transform offset, can't this be fixed?

 

No, I did not freeze them.

The errors came from slightly different joint positioning throughout the models.
I ended up putting all clothing components over a new rig with correct realworld scaling, trying to let them intersect each other they intersect each other as much as possible. Like putting clothes on a puppet.
Then I bound all clothes to copies of the new rig and importet their old weightmaps.

works now as expected
