Because Project From View only works from our current view, then you would have to manually guess how to move the edge loops to decrease distortion. But also the sphere is just an example. I work with more complex objects, and even though it is not the end of the world, it can be a problem sometimes, so I thought I would mention it.
For example I am modeling a human head, and even though the model is symmetrical, the UV map will not be symmetrical. So for instance the texture is slightly more stretched or distorted on the right side of the mouth. In this case it is not a problem because it is barely visible on the organic skin, but with other types of objects or clothes it could be more visible and require unnecessary work. I know it is possible to somewhat work around this maybe by mirroring the model …, but that would be a lot of work and not worth it.
I downloaded the trial version of Maya to see if it has the same issue (don’t worry I’m not moving to Maya). It is not completely straight either, but it is much more symmetrical, on the other hand it seems like the quads of the UV are too thin in Maya which will cause more distortion.
Here is the exact same unwrap but in Maya:
Anyway, it is a minor issue and I just thought there could be an option to make it symmetric automatically.
Thanks for the help
