I didn’t realize you could already pose in nomad (yes, you can). I can mask off an area I want to pose and invert the mask. Then I blur the mask. Next I adjust the pivot to the root of the area I want to bend. It works very well.
Now, it may be simpler to add a posing feature by adding the ability to save a mask selection with a name (and perhaps the pivot position). Even better, perhaps we could save the current model settings (pivot position and all, or selected properties we want to save).
