Why we like it

Stands out in the superhive library for reducing action constraint setup to four steps while leaving files that continue to work without the add-on installed.

What is Action Constraint Builder - Set Driven Key?

Action Constraint Builder - Set Driven Key gives Blender riggers an interface for building action constraints, inspired by Autodesk Maya's Set Driven Key. It's part of the Set Driven Key - Value Bundle, which also includes the Shapekey Driver Builder.

The add-on reduces action constraint setup to four steps: load the controller driver object or bone, load the driven target object or bone, pose the object or bone, then set the driven key. It suits complex rigs that need predetermined poses or actions, with applications including wing folding, facial rigging, mechanical transformation, and hand gestures.

Because it works as a setup and builder tool, the add-on only creates the constraints and isn't required for the file to function afterward. Files can be sent to someone without the add-on and the constraints still work. TinkerBoi reports a wing folding mechanism set up in 54 seconds, and a comparison where the same constraints took 4.44 minutes manually versus 59 seconds with the add-on. Documentation is available, and support is offered through Blender Market questions or the Discord server.

Frequently asked questions

Do files still work if I send them to someone without Action Constraint Builder - Set Driven Key?

Action Constraint Builder - Set Driven Key works as a setup and builder tool, so it only creates the action constraints and isn't required afterward. Once the constraints are set up, you can send the blend file to someone who doesn't have the add-on installed, and the constraints will still work without a problem. TinkerBoi describes this as no vendor lock, meaning the file's functionality doesn't depend on keeping the add-on present after setup.

How many steps does Action Constraint Builder - Set Driven Key take to set up a constraint?

Action Constraint Builder - Set Driven Key simplifies action constraint setup into four steps: load the controller driver object or bone, load the driven target object or bone, pose the object or bone, then set the driven key. According to TinkerBoi, setting up the same action constraints manually takes 4.44 minutes, while using the add-on brings it down to 59 seconds. A wing folding mechanism was set up in 54 seconds using this workflow.

Is Action Constraint Builder - Set Driven Key free?

Action Constraint Builder - Set Driven Key is listed as free here in our catalog. Licensing terms can change, so check TinkerBoi's page for the current details. The add-on is also part of the Set Driven Key - Value Bundle, which includes both the Shapekey Driver Builder and the Action Constraint Builder, if you're looking at the wider set of tools. For questions, support is available through Blender Market's Ask a Question feature or the Discord server.

Where can I get support for Action Constraint Builder - Set Driven Key?

Action Constraint Builder - Set Driven Key offers support through the Ask a Question feature on Blender Market or by joining TinkerBoi's Discord server. Documentation is also available to learn more about how the add-on works. The tool covers applications such as wing folding, facial rigging, mechanical transformation, and hand gestures, and a demo video is available if you want to see more before setting it up.
