Today I finally figured out the buffer for this prop appears to be offset to the right. The handles are wide on the right and the center rotation handle is also offset. I tried another download today of the same prop and it too is offset. My other stars / props are not offset but centered. I am assuming the cell count can be changed to tighten up the right side. I open the node layout and there are 11 extra blank cells on the right side.
I clicked on the count of 95 across to change it to 84 with no success with the model both locked and unlocked. I assume I am doing something wrong.
