I can't move the finger from makehuman model with rigs I have selected the finger that I want to move. I clicking in Transformation manipulators:Rotate and Gimbal.

When I press "R" to move it. Nothing happens.
The green colour from the finger selected is moving but the finger doesn't


When I try to move the arm. The rigs are moving but not the arm.

Thank you so much

For a rigify rig the fingers curl is controled by scaling S. This automaticaly rotates all finger bones at once.
