Assessing the coordinate task

I’m determining whether the claimed grass reference is valid and whether the chest’s vertical coordinate was misread. I’ll inspect the scene’s block grid and compare the chest’s relative position rather than assuming identical height.

Identified the image’s target coordinate****Estimating vertical placement

I’m comparing the grass terrace with the chest’s supporting surface. The initial same-height assumption looks unreliable, so I’m checking whether the chest sits several blocks lower than the chosen grass reference.

Correcting coordinate assumptions

I’m narrowing the issue to two likely errors: treating reflections as valid orientations and assigning the chest the same Y level as the reference. I’m testing only physical rotations, then separating horizontal offsets from vertical layers.

Validating the mapping

I’m separating texture-state matching from geometric placement. The reference coordinate may be plausible, but the chest still requires a measured block offset and the correct physical orientation, not a guessed diagonal shift.Searched 1 website
