Somebody surely must have suggested this before, but I can’t find a topic for it right now and I just found a scenario where this seems pretty critical:
When resetting shape key vertices according to the method on the page below, I think it’s currently impossible to fade in an affected area smoothly in one step. Only workaround I can think of is to manually grow the selection and then run the “blend from shape” command between each step…
There should perhaps be a switch between “proportional editing” and “proportional selection”. Alternatively, a way to paint vertices for selection using a brush?
