Welcome

Thank you for purchasing SecondNature!

SecondNature is an animation add-on designed to automate the process of creating secondary motion by driving bones from existing F-Curves. Instead of spending time setting up complex drivers manually, you can generate and tweak them in just a few clicks.

Whether you're animating characters, creatures, clothing, accessories, or props, SecondNature helps you stay focused on the animation instead of the technical setup.

Installation

1. Open Blender.
2. Go to Edit → Preferences → Add-ons.
3. Click Install.
4. Select the downloaded ZIP file.
5. Enable SecondNature.
6. Save Preferences.

Getting Started

Step 1 — Select a Bone from Rig

Choose the object or bone that already contains the animation you want to use.
And then specify the channel that will drive the Poses

This animation becomes the Master F-Curve.

Step 2 — Choose Driven Bones

Select one or multiple bones that should receive the secondary motion.

There is no practical limit to the number of driven bones.

Step 3 — APPLY

Click Apply.

SecondNature automatically creates the NLA STRIP while keeping your original animation untouched.

Step 4 — Adjust Settings

Fine-tune the generated motion using:

• Influence
• Delay

These settings let you create everything from subtle overlapping motion to exaggerated follow-through.

Non-Destructive Workflow

SecondNature never modifies your original animation.

Everything is created through Blender drivers, meaning you can:

• Undo
• Redo
• Delete NLA strips
• Edit settings anytime

without losing your animation.

Advanced Workflow

If you're already comfortable with Blender's animation tools, SecondNature becomes even more powerful.

It works extremely well together with:

• NLA Layers
• Constraints
• Existing Rig Controls

You can combine these systems to build complex procedural animation setups.

Tips

✔ Animate the main motion first.

✔ Add secondary motion after your primary animation is finished.

✔ Small values often produce the most natural-looking results.
