Sorry if this is a noob question, I'm very new to 3d modelling and animation.
I modelled a humanoid character with a mirror modifier.
I want to use a shape key to realistically animate the elbow when the forearm is rotated.
I created the shape key on the left side and used the left forearm bone as the driver.
The problem is, that if I rotate the left forearm, the shape key is also applied to the right elbow, even though the right forearm bone isn't moving.
Is there a way to use a separate driver for the right side? I don't want to apply the mirror modifier, as I will need to do some additional modelling later.
