I created a tooth mesh using a geometry node. enter image description here

This was created with the meaning that the teeth can be moved freely by editing the external mesh line. However, it doesn't rotate as I expected. This is because the rotation of the plane is not reflected on the teeth. enter image description here

I thought about reflecting the rotation of the plane with a geometry node. However, I extracted only the x-axis of object info's rotate, but the value is 0. What the heck is going on? enter image description here

Ideally, when the plane rotates, the teeth also rotate in the same way individually. You may be wondering why I don't apply a geomtry node and rotate it as a mesh, but I'm sorry, but I want to control this tooth with a mesh line.enter image description here

  • $\begingroup$ When I click on the object "Plane", the Translation data says it is located at (0, 0, 0) and rotated (0°, 0°, 0°). And that's the values you get from the Object Info node with the Location and Rotation. This is object information, how you manipulate the mesh in Edit Mode is irrelevant for that node (well, not completely - if you instance something on the vertices, their locations will be used). But vertices themselves have no own rotation, only position data relative to the object they belong to. $\endgroup$ Mar 21 at 15:15
  • $\begingroup$ I do not understand your problem: when in Object Mode I am rotating around X axis the object named "Plane", I can check that the value displayed by the Viewer node is no longer 0. Your second picture let me think that you are rotating in Edit Mode. But the Object Info node output sockets are providing transformations in Object Mode. As Gordon explained, rotation in Edit Mode is changing vertices, not the global transformations of an object. $\endgroup$ Mar 21 at 21:09
  • $\begingroup$ @StefLAncien That's it exactly, as I said his object is not rotated, it's just an edited mesh. $\endgroup$ Mar 21 at 22:17
  • $\begingroup$ Thank you, everyone. I understand that object info node is information in object mode, not rotation in edit mode. $\endgroup$
