Dun worry for the magnets, since inside poser they are props that exist in the runtime folder, once all the work is done one can edit the .cr2 file to reference the components of the magnets to lower resolution props or even null props, u will only need the ERC control to dial . . . BTW, kuroyume, have u tried to set up an IK for AM in the arms or u r just saying how to create one but haven't done the attempt? 'cuz everytime someone tryies to set up a chain like: Slhd-UpArm-ForeArm-Hand u end up with weird results . . .
