I have created an object using geometry nodes. I control its input node "String." I want to control the position of this object based on the x dimension, but when I change the string (therefore, the dimensions of the object), it does not update immediately. Instead, it keeps the location of the previous string, and only when I rerun the script again, the object moves to the correct position.

import bpy

Texts = bpy.data.collections["Texts"].objects

bpy.data.node_groups["Geometry Nodes"].nodes["String"].string = 'The Text I Want To Change'

Texts[0].location[0] = 0 - Texts[0].dimensions.x/2

  • $\begingroup$ This works immediately for me. What Blender version are you using? I'm on 3.3.0 $\endgroup$

  • $\begingroup$ I use 3.3.1, so it should not be a problem. Have you also tried to change the string after the first use? I edited the question, so my problem is more clear. $\endgroup$
