Oh, mighty Blender elders.
I'd like to know if this is a bug, or intended behavior.
What is going on
I have three textures with different aspect ratios. 1:1, 2:1, 3:1.
But when unwrapping, the UV map aspect ratio is always based on the image selected in the shader editor.
It seems that unwrapping depends on your shader editor image texture, not the texture in the UV editor.
So, in some cases, there's no way to match the correct aspect ratio.
2:1 in UV editor, 3:1 in shader editor. And no way to match the correct ratio.
This concerns all UV unwrap methods and projections.
Correct aspect ✓ doesn't work either - it only switches to 1:1 ratio.
Even after removing an image from file, Blender still unwraps in it's ratio.
Is this intended behavior?
Or is this a bug that should be reported?
