I have an model with an armature. On several bones are custom properties which are used in drivers.
At the end, the model and the armature should be linked in another scene and the custom properties are used to control certain functions of the model.
My problem now is that I want to control a color of an material node by means of a custom property. For that I added the hex value of the color to the property to use this value in a corresponding driver which should set the color of the material node. But the variables in the driver only accept numeric values and hex is a string. Is there any other way to control a color in a linked object?
