I have a robot arm consisting of a shoulder, bicep, elbow and forearm. The shoulder and elbow are circles and the bicep and forearm are rectangles. I have added two bones the first anchored to the shoulder and the second anchored to the elbow. When I move the upper bone, attached to the shoulder the arm moves without distorting the shapes, but then I try to move the forearm, the circle representing the elbow distorts. How can I stop this from happening?

I am using v5 of Anime Studio

Thanks,

the best way if you want no distortion is to manually assign each shape to a bone. while on the vector layer pick the 'bind points' tool (I) and alt+click on the bone for the upper arm. Now select the shoulder and upper arm shapes and hit the spacebar. This assigns them to that bone and dissables other bones warping influence over those points.

Now do the same with the elbow/lower arm shapes, attaching them to the lower arm bone. You should have a clean arm with no distortion now.

Once you do this, you might also want to reduce those bones area of influence down to nothing so that it doesn't effect any new shapes you create.

go through all the help tutorials that come with AS, they will really help a lot!

Thanks for the help. It appears I was on the right track and had already tried manually binding the bones, I must have been doing it wrong.
