I am creating a custom node group for the Compositor, and I would like to control the size of a cloud texture with a driver within the node group. However, after appending the node group to a new blend-file, the driver is no longer working. I have to manually copy and paste the drivers again for them to work. This is not user-friendly, especially when sharing the node with others. Is there something I am doing wrong?
