I created character in bledner and now I want to retarget it to mixamo animations, but when I run retarget than my character fly away I used auto create retarget chains for both characters. When I tried to retarget my character to Manequinn it worked fine so I think the problem is related to root bone. I tried to retarget my character with root bone as actual root but not pelis and it worked fine until I exported animation.
Link to video where I show problem in editor: https://youtu.be/nSf44ezYMpE
How to fix that and accually retarget mixamo animations to my character?
