Hello there, how is everyone? I have a question which is a issue, my character’s armpit is deforming weirdly in Unreal while is it is fine in 3ds . The other limbs are deforming correctly but just this armpit area. Does anyone has any ideas why this is happening.
-do you get any warnings when you import your mesh?
-double check if everything is correctly -> are all vertices assigned correctly, is the rotation of the bone right,… 
No warnings and believe the bone is acting properly
dw, found the problem. when exporting the mesh and skeleton from . have to have the tpose in the first frame
Well done on finding out the error, and thanks for getting back to us and letting us know what the solution was.
