Shape Key Manager Pro earns its place in the superhive library by folding several slow, repetitive shape key tasks in Blender into single-click operations, from duplicating and mirroring to retargeting drivers across a character's two sides.
Shape Key Manager Pro is a Blender addon built to speed up shape key rigging. Setting up drivers for one side of a character and then repeating the same work for the other side is slow going; this addon duplicates and mirrors shape keys while maintaining and retargeting their drivers, turning multi-step processes into single-click actions.
Duplicating a shape key in Blender normally means turning off every other key and creating a new key from mix, and mirroring can miss vertices. The addon handles both on a single key or on multiple keys through a filter. It can assign a selected vertex group to newly duplicated keys, copy and rename drivers across sides using a .L/.R naming convention, and convert selected objects with matching vertex indices into shape keys on the active object.
Later updates add a beta Driver Creation Tool with factor, reverse-influence, and custom-expression settings; a way to copy shape keys between objects with mismatching vertex counts using proportional editing; and parent-child relationships between shape keys for deformation-based setups. Documentation is included.
Shape Key Manager Pro is best for blender artists rigging character shape keys and drivers across both sides of a mesh.
Shape Key Manager Pro is completely free to download and use.
Shape Key Manager Pro copies and renames drivers automatically when you follow a naming convention, such as .L for left-side bones and shape keys and .R for the right side. Copying a driver in Blender normally means jumping between windows, pasting values, and manually editing bone names and paths. With a consistent convention in place, the addon changes the driver's bone and path from one side to the other, so you can set up drivers on one side of a character and apply the mirrored result without repeating the process by hand.
Shape Key Manager Pro can copy shape keys from one object to another even when the vertex counts do not match. You add a temporary shape key to the target object and use proportional editing to move it to match the source object as closely as possible; the addon then grabs the nearest vertex on the source for mapping. Two options refine the result: Limit to Selected Vertices restricts copying to selected vertices in the target to prevent unwanted deformation, and Smoothing Iterations applies corrective smoothing. The developer suggests adding a subsurf modifier to the source object for denser, smoother results.
Shape Key Manager Pro includes a Driver Creation Tool, added in update 1.1 and released as a beta that will undergo changes. It adds a driver to the selected shape key using standard variable types and settings for controlling influence. Variable Factor multiplies the driver by a factor, and Variable Reverse Influence reverses the driver's influence, so an X-location driver reads as full influence at zero location and none at the factor value. Driver Expression lets you write a custom expression that overrides those two settings.
Shape Key Manager Pro is listed as free in this catalog. Licensing terms can change over time, so check the developer's page on superhive for the current details before you download. The addon is published by CodyWinch and comes with documentation, and a demo video is available if you want to look further before installing. For any questions about usage rights or updates, the developer's page is the most reliable place to confirm the latest information.
