  2. As for retarget based on standard skeleton choose humanoid rig
  3. choose the same thing in my character mesh
  4. choose animation that i want to retarget and here is what i got

first of all i do not see my character in target slot of retarget window
and here is the result of retargeting

It looks like mesh become so big that he even goes beyond environment sphere.
