I have a GN node tree with an output value as a float.

enter image description here

Blender tells me the path to it, which is great. And i got...if i execute it...an "x" ...umpf.

Hoped for a value. How do i get the value?

You need to refer to the object attributes, so if the attribute is a vector you can do:

obj = bpy.context.object.evaluated_get(bpy.context.evaluated_depsgraph_get()).data


You might need to adjust the indexes for your attributes.

    $\begingroup$ Hi! Is there a systematic way of chasing this kind of information down, or is it just something you have to know?, and is there a way of guaranteeing the index? e.g finding index for name? $\endgroup$
