Physic Asset creating bone moves far away?

I’ve tried different methods on importing character from Blender to UE4 and can’t figure out why Physic Asset is going crazy even I setup from scratch. On the example I just added 3 bones connected to each other and when I select the neck and hit simulate the head moves far away.

Does anyone know how to fix this?

Hello, did you try disabling interactions between them?

Has anyone figured out a solution to this?

Nope. I had to switch to another job…

Scale of the scene must be 0.01. Chceck this tut. It is not exactly horse but everything needed to setup skeletal mesh from scratch How to get wheeled vehicle from Blender to Unreal Engine 4 from scratch [OLD] - YouTube

Thanks! The last time I made changes I exported with scale of 1 but when imported into UE4 I scaled up my mesh to 50. cannot confirm the solution
hope it works
will test the scale of 0.01 in future projects
