unreal.RigControlValue() ?

I am creating a python script for ControlRig.
But I`m stuck on how to set “maximum_value” for a “unreal.RigControl”.
It takes a argument of a “RigControlValue” object.
I can create such object with unreal.RigControlValue()
But how do I actually set the value ?

Thanks.

Hi, I’m facing the same problem. Do you find any solution?
