Hello everyone, coming from Blender 2.65, I’ve observed a strange behavior (bug?) that is happening in 2.69 with the “Unwrap” option in UV Unwrapping.
When unwrapping a basic cube with the “Unwrap” uv unwrap mode, a result of 6 overlapping squares will be produced. Using other unwrap modes will overwrite this result with a new result (as will overwriting those results with another “Unwrap” procedure).
Unwrapping the cube for the 1st time with “Unwrap” will yield the expected 6 faces stacked on top of each other result. However, if any other unwrap method is used, or if the basic Unwrap is not the very first unwrap used, nothing will happen (the UV layout will remain as it was). All other uv unwrap modes seem to work correctly, but the basic “unwrap” method only works 1 time (if you use it first) and will not overwrite the previous unwrap.
I’ve tried changing the mesh, selecting and deselecting different combinations of uv/mesh faces, nothing I have tried will make “Unwrap” work more than 1 time. Any ideas?
