I have a truncated cone, open on both sides, laced near the top, with rims/curves along the top and bottom edges:
However, whenever I unwrap the object using the cylinder method (which seems to give the best layout solution overall), several faces that are adjacent on the model appear on the other side from their counterparts on the UV map:
This happened to the faces near the marked seam, but removing the seam - having no seams at all - results in the exact same layout.
The model does not have any modifier.
Does anyone know why this happens and how I can prevent it, or change this behaviour during unwrapping?
