yonghao lv (Atticuslv) added a comment to T99964: Can not get eval obj's attribute in get/set function.

So what I expect is I can read bpy.data.objects's attributes without linking them to the scene. If we can read their location, we shounld be able to read their attirbute.
Seems now the deps graph no longer consider the object not link to the scene?

yonghao lv (Atticuslv) added a comment to T99964: Can not get eval obj's attribute in get/set function.

I still don't understand the issue. It prints {'factor': [0.0, 0.9999999403953552], 'length': [0.0, 0.0]} for me when Cube.001 is selected, which means the attributes are correctly retrieved.

Can you clarify this?

Can you clarify your last point? Which object wasn't linked to the scene? The one named Motion Control-MotionPath? Is that in the second file you shared?

In your second file, if I connect the Domain Size node to the bezier curve geometry output, it prints the attributes as expected. Could this be the issue or was this just a mistake while preparing the file?

Regardless, I don't think using with contexts and depsgraphs in RNA setter and getter functions is safe.

The second file, this is how it work

  1. run the script
  2. go to console to slide the test value
  3. select the 'Cube', you can see its value print in console
  4. select the 'Cube.001' who reference from a curve object , it will not get the attribute in console (nodegroup: transfrom attribute from curve to mesh by index, it works well in 3.2)

I notice that not all situation is suitable for small default value. Some company use 'mm' to produce their 3d print wax model (for example, jewel), so 1mm in these scenes is fine.
Maybe just set a color tips on the render view(also on the set radius node) , and exclude the curve object from rendering.
