How to I deal with unwrapped UVs orientation?
- Delete the default Cube.
- Add a Cylinder
- Edit mode and edge select the Top and the Bottom and a single connecting edge.
- Make them into seams
- UV Unwrap (standard Unwrap mode)
The unwrapped UV now shows two circles above a row of quads. I can save this and open it in an image editor and paint over those areas and get the texture to align on the cylinder back in blender.
But, the pattern(just happens to be text) that was inserted in place of the row of quads is now upside down on the model. Any attempt to flip or align just makes things worse, from upside down to mirrored or the Top/Bottom not aligning.
So my real question is how could I have known that the quads represented an upside down view of the world?
Do other blender users export UVs and mark them with arrows and colours just to see how they align on a model before actually painting for real?
I tried selecting the edges in step 3 in different orders before making them into seams and it made no difference.
I also looked at the Normals but they appear to be only Inside/Outside not Up/Down.
