Quoting myself in another thread.
In the following situation:
This “Ringed Loop Selection Pattern” based unbevel can’t work. If you can add geometry as follows:
Then it can easily work.
Note: you can easily achieve this using the Offset Edge Addon.
End quote.
Is it possible to add a slider with distance weigth into unbevel?
See therefore the Woolfy13 post in the mira thread: bevel distance weight
Such a mechanic is not exactly un-bevel, but modifying the bevel. Definitely achievable but there will be cases where it could produce bad results.
