I requested once a slider, but I think this would be best and intuitive.
Tap hold and drag mask blur button is increasing the blur amount.
That would be monster helpful. In my ideal world it would look like applying Gaussian blur and increase value.
That would be the end of endless tapping on blur like a woodpecker.
More really helpful masking options:
A gradient brush would be nice, for masking and painting. Tap start, tap end point, hit green dot like path, gradient window pops up, adjust gradient - validate.
Mask “painted vertices”
Adjustable cavity mask. For modelling it is very useful as well.
Smear, optional for mask.
Mask layer changes - like super cool extract function.
Layer extract algorithm for extract mask? This is very hypothetical, but isn’t extract layer producing cleaner meshes than extract mask?
