Help! - Mesh anim deformation in IOS export different than editor and maya

When i create a build for IO the character’s mesh deformations on my character deform way differently than when its playing back in the editor. Is there some setting in a IOS export that may be causing this? Why the big difference?

Also, this mesh has multiple geometry parts, could that be part of the problem? But then why does it work fine in the editor?

Please help!

Take a look at Edit/Project Settings/Quality settings/Blend weight, for IOS this setting is set to 1 bone by default. It may help you but will surely decrease performance at the same time
