Using Geometry Nodes I know that I can sample a curve and move an object along this curve. However, this approach doesn't affect children of the object moving along the curve.
For this purpose I wanted to use geometry nodes output attributes as a driver for my object that I want to move along the curve.
Now say I want to use _X attribute as a driver. Is this possible? I'm copying data path e.g. for _X and it looks as follows:
modifiers["GeometryNodes"]["Output_2_attribute_name"]
But when I try to use it in a Driver I get always zero. What do I miss?
