Sits in the blender_extensions library at rank 50 and earns its place for turning the simple deform modifier into a gizmo-driven, one-click workflow. Compatible with Blender 4.2 LTS and newer, under GPL v3.0 or later.
Simple Deform Helper is a Blender add-on that enhances the simple deform modifier with a visual, gizmo-based workflow. To display the gizmos, select an object and add a simple deform modifier. From there, a red gizmo sets the upper limit, a green gizmo sets the lower limit, and a purple gizmo controls deform strength.
While dragging a gizmo, press X, Y, or Z to lock to an axis, or hold Ctrl to keep the relative distance. You can change the origin control mode in tool settings to adjust limit behaviors, and scroll while dragging to change it quickly. The add-on works with mesh, lattice, and curve objects, matches upper and lower limits automatically across all modes, and includes one-click correction of bending deformation orientation, twisting in bending mode, and adding and deleting keyframes. A Show Gizmo toggle is mapped to Ctrl+`.
One limitation to note: it does not support multiple simple deform modifiers well, especially where deformation areas overlap. It is compatible with Blender 4.2 LTS and newer and released under the GNU General Public License v3.0 or later.
Simple Deform Helper is best for blender artists working with the simple deform modifier who want gizmo-based control over bending, twisting, limits, and deform strength.
Simple Deform Helper is completely free to download and use.
Simple Deform Helper is compatible with Blender 4.2 LTS and newer, so version 4.2 is supported. The current release is 0.2.7. Because it enhances the simple deform modifier, you work with it directly in the 3D view once an object and a simple deform modifier are in place. For installation, the developer notes that installing from a downloaded ZIP can cause an error and recommends downloading it from the releases page on GitHub instead.
Simple Deform Helper displays its gizmos once you select an object and add a simple deform modifier to it. Three colored gizmos then appear: red for the upper limit, green for the lower limit, and purple for deform strength. While dragging a gizmo, press X, Y, or Z to lock movement to an axis, or hold Ctrl to keep the relative distance. You can also switch the gizmo display with the Show Gizmo shortcut, Ctrl+`.
Simple Deform Helper does not support multiple simple deform modifiers well, and the developer specifically notes issues when deformation areas overlap. If your setup relies on stacking several simple deform modifiers on one object, expect limited results in those cases. For single-modifier work, it covers mesh, lattice, and curve objects, with automatic upper and lower limit matching across all modes and one-click correction of bending deformation orientation.
Simple Deform Helper is released under the GNU General Public License v3.0 or later. This catalog lists the add-on as free; for current licensing and terms, check the developer's page on GitHub. The extension does not require special permissions. You can get it from the project's releases page, which the developer recommends over installing a downloaded ZIP directly to avoid installation errors.
