Hi all !
Could anyone please tell me why smart UV project is unable to have proper aspect ratio ?
Here’s the thing:
this is just a 1:1 aspect ratio stretched to 2:1 A/R image.
Is there a workaround for this ( veeeeeeeeery old… before 2.79 ) bug ?
Thanks and happy blending !
Here’s a semi-quick workaround:
- smart uv project
- seams from islands
- unwrap
hi @SterlingRoth
Thanks for your answer !
I didn’t know the seams from islands feature
However, this seems not to work. I still got my wrong UV aspect ratio
hm, does the object have a material that references that (or another) texture?

Yes there’s a material with various aspect ration textures…
Indeed, i think i found a way…
It is weirdo as often in blender but at least i seem to be able to reproduce the thing.
The unwrap process just dont care the A/R of the texture in texture editor. It ONLY cares the ACTIVE texture node in nodes editor.
This means if the tex in image editor is 1:4 and the active ( or last ) texture node in node editor is 2:1 then the UVs will be unwrapped according the 2:1 aspect ratio.
Thais is imho the worst choice that could have been done but at least, this can be reproduced…
Now i just have to build a small script to fake the selected texture in nodes editor and this shoud do the trick…
Oh and, the ‘seams from islands’ work perfectly for this
Thanks a lot and happy blending !

And finally i managed to bake my 2:1 piece of AOmap for my project
Thanks a lot @SterlingRoth !!!
Happy blending !
Back there just to post a lil update.
I’m sooooo glad the unwrap aspect ratio enigma has been solved !
Now with a lil piece of script, i can just unwrap on non 1:1 images and have proper proportions on my unwraps !!!
This is awesome !
Happy blending !
