UV Mapping Misalignment

Hello everyone,

I’m working on a task that involves extracting values from a texture to displace a mesh. However, I’m struggling to understand why the UV mapping is not aligning with my expectations.

  1. Expected Outcome (Number 1): It’s only when I insert a surface node between the rectangle shape and the mesh node that I achieve the UV mapping I desire. This orientation aligns with the source image
  2. Unexpected Behavior (Number 2): Interestingly, when I connect my rectangle shape directly to the mesh node, the UV mapping appears rotated.

Could anyone shed light on this situation? What am I missing or misunderstanding here?
