Falloff Lens earns its place as a focused viewport utility: it turns Blender's proportional editing radius into a visible guide without touching mesh data, so you can judge the affected area before committing to a transformation.
Falloff Lens is a Blender 4.2+ add-on that shows proportional editing influence directly in the 3D Viewport before you move, scale, or rotate geometry. In Mesh Edit Mode it displays weighted influence across selected vertices, edges, and faces, while Object Mode previews influence across visible object origins when you work with multiple objects.
A cold-to-hot gradient reflects influence strength from low-impact outer areas to high-impact regions near the selection, backed by a visible radius boundary, optional semi-transparent face tinting, and weighted bounding boxes around affected objects in Object Mode. You can drag the radius using the Adjust Falloff Radius tool or the Ctrl + Alt + R shortcut, and a viewport-aware projected preview is approximated in screen space, updating as the view changes. The overlay is non-destructive and never modifies mesh data.
For heavier scenes, Falloff Lens adds refresh throttling and maximum vertex and object limits, and you can set default overlay behavior in the add-on preferences and apply it to the current scene. Enable the overlay from the sidebar or the View menu to preview the affected area before committing to a transformation.
Falloff Lens - Proportional Editing Influence Visualizer is best for character modeling, organic sculpt-style edits, environment modeling, and object layout adjustments where soft transformations need precise control.
Falloff Lens - Proportional Editing Influence Visualizer is completely free to download and use.
Falloff Lens is built for Blender 4.2 or newer, so Blender 4.2 and any later version can run the add-on. It works within Blender's existing proportional editing workflow: enter Mesh Edit Mode or Object Mode, select your geometry or objects, enable proportional editing, then turn on the Falloff Lens overlay to preview the affected area. Because it supports both Mesh Edit Mode and Object Mode, it fits mesh editing and multi-object layout tasks alike. For the exact supported versions, check the developer's page before installing.
Falloff Lens includes a built-in Adjust Falloff Radius tool, and you can also use the default Ctrl + Alt + R shortcut to drag and set the proportional radius directly. The add-on draws a visible radius boundary in the viewport so the proportional editing range is easy to identify, and a cold-to-hot gradient shows influence strength from low-impact outer areas to high-impact regions near the selection. This lets you settle on the radius and falloff curve before performing a transformation.
Falloff Lens is a non-destructive overlay that does not modify mesh data. It only draws a viewport visualization of proportional editing influence, using the cold-to-hot gradient, optional semi-transparent face tinting, and, in Object Mode, weighted bounding boxes around affected objects. Because the tool never alters geometry, you can preview the affected area freely and turn the overlay off at any time without changing your model. That makes it safe to leave enabled while you judge which vertices, edges, faces, or objects fall within the radius.
Falloff Lens is enabled from the sidebar or the View menu once you're set up. The typical workflow is to enter Mesh Edit Mode or Object Mode, select the geometry or objects you want to edit, enable proportional editing in Blender, set the radius and falloff type, then switch on the Falloff Lens overlay to preview the affected area before transforming. You can also customize default overlay behavior in the add-on preferences and apply those defaults to the current scene.
Falloff Lens is listed as free in this catalog, so there's no purchase required to add it to your Blender setup. Licensing terms can change over time, so it's worth checking the developer's page for the current details before you download. Once installed, it works alongside Blender's built-in proportional editing and includes performance controls such as refresh throttling and maximum vertex and object limits for heavier scenes.
