Help rotating arm correctly

This is what happens:

The video is all about R15, and the current guy here is using R6.

Everyone is confused. R6 aren’t compatible with this type of grip (That’s what i called). And you have to manually add something to R6 body parts.

Usually, the idea is to make some test on client side first and add some weld to the Arm and adjust the C0 Positions.

But always remember to know where the positions are going, by finding the negative and positive position to move the arm to the correct position. Here’s the idea here in the Photo.

After that. Add a mini part in the arm and set it to the back of the arm in the middle, like you know…

And then when the arm C0 is about to rotate, you can maintain the rotation base on the camera’s rotation.

Forgot to mention that you need to change the PivotOffset to rotate correctly.
