Primarily I am a Maya user and I need some help to understand blender's unwrapping tool. By default Blender unwrapping tool gives suboptimal results with a lot of stretches on the inflated areas: extremely distorted nose, lips and ears. (I added Maya's default unwrapping result for comparison. It perfectly shows how the face should be unwrapped). So my question is: how do you fight that kind of stretches? Are there any better plugins to unwrap or how can I control those problem areas without ruining others?
Try using the Magic UV add-on, which is already installed in blender, u just need to enable it... Here's a short video of UV symmetry with the add-on: https://youtu.be/GjRx1C1r-Mg
And here are some UV tips to improve the UV unwrapping: https://youtu.be/DhFOJrLGBDs
Hope it helps ^^
