Anim Dynamics makes mesh insanely small?

Rasmus_Hauschild · November 13, 2020, 1:00am

Hi,
I am trying to add dynamic animation to my character’s tail, but as soon as I enable the anim dynamics node in the anim graph, the tail becomes extremely thin in the x and z direction (see image 1), while the y-direction seems unaffected.
I had a similar problem when setting up an IK foot system for the character, where I had to scale the effector location down 100 times, so I imagine this might be similar, but I can’t for the life of me figure out how. The model is made in blender 2.9 and exported using the recommending settings - scaled applied and everything.
The aim dynamics node is set up as shown in image 2.

Any assistance would be greatly appreciated!

if anyone need just change simulation space like bone relative or root
