Hi, I am using Mgear 4.0.9
After I have replaced the shape of a control and extracted them. When I do a rebuild of the rig the shape is there and correct. But instead of having the color that is specified for the component, example (FK controls on the left), it just has the base basic Maya color of a curve.
I see as a work around I am able to go into the shape manually to what it should be. This does take a lot of time though.
