Selection Falloff requires Blender 4.5 or newer. It has been tested on Windows. macOS and Linux have not been tested, so compatibility with these systems is not guaranteed.

Place and adjust one or more falloffs in the scene. Each vertex in your selection receives a weight based on their combined influence. Supported operations apply their full effect at 100% weight, with a proportionally reduced effect at lower weights.

Blender’s standard modelling tools were not designed to accept arbitrary influence weights for individual vertices from an add-on. This limitation is not specific to Selection Falloff, so simply passing the calculated weights to the existing tools was not an option.

Selection Falloff therefore provides custom, weight-aware versions of the supported modelling operations. They follow Blender’s familiar controls and behaviour as closely as possible, while applying each operation according to the vertex weights.
