Looking for -proven- retargeting Infiltrator/UE skeleton solution

Hello

I have some experience with retargeting, also studied many tutorials, but I still have errors after skeleton retargeting. I['m trying Infiltrator skeleton to UE - many problems. I tried simple and advanced mode with all bones, etc. I know Tesla dev tutorial but still not correct retargeting (maybe his tutorial is obsolete now).

Pleas help here or posting links - all working answers will be approved.

Thank’s ++

Well, mission impossible in UE?

As I understand, retargeting is broken and can’t be used as solution for production quality animations even with other skeletons used by Epic in projects like a Shooter, Infiltrator, Matinee etc not mention totally different skeletons? It works only with exactly same skeleton just little bigger like in showcase in Content Exmaple right?

retargeting seems to work fine for me in 4.17. have you watched the tutorials by epic on retargeting? thats where i learned the basics of it.

Thank’s for reply @ThompsonN13 Yes, I studied Epic strams, tutorials and not only. I see they skips important for me details, is possible I just do something wrong.

In this post https://answers.unrealengine.com/questions/790832/problem-with-perfect-retarget-skeleton-from-sequen.html I have screens with samples where I have problems, maybe this can help. I can also post more screens with another meshes, skeletons.
