MMD Multi-Arms Bone structure download by Pikadude31451 MMD Multi-Arms Bone structure download by Pikadude31451
I'm really sorry that I haven't been able to upload anything in a long time. I wanna start again, but I'be been swamped with work and commission stuff. 

This is just a quick little thing I did while waiting for my fiends to pick me up. I made a bone structure that will move all the arms at ones. Like, if you load a motion or pose, all of the arms will move in unison. I've had this idea for a long time, and i'm considering using it on my Rosalina model, so she can have Luma with her, and he won't have to be loaded separately. But i've had this idea ever since I wanted to load an Oliver model along with a James model like this. I just finally managed to sit down and fiddle with the bones. (The fingers pose alone with the original arms, too)

Feel free to edit, add more arms , or move them around. the IK bones in the back are used to move the extra shoulders, like if the aren't stacked perfectly like this. Also fee free to make these bones are re-rig anything you're making. This is really easy to edit to add more arms - you can just re-name the ones you load, and then load the original - the ones that are remained will be considered new bones, but still follow the original arms.

The arms are Animasa Meiko. I just included those for the sake of people being able to see how they are working with parts. Feel free to remove the Animasa arms.

You can credit be for the structure, but it's okay if you don't - it was only about an hour or so of work.

Have fun~

let me guess the "normal" arm bones are still wel... normal and the added arm bones are inflict rotation ones with the IK parent set to the normal arm bones >.>

You were almost perfect, haha - the IK are for the new shoulders, just so you can move them out of the way if they mess up the motion data or just need to be somewhere else. When I say normal arm, I mean the arm that is in charge of moving the rest of the arms - each of the bones in the "Extra" arms is rotational bone that follows it's respected original arm bone in the same way.
