Demo Setups
===========

The **Demo Setups** section at the bottom of the N-panel provides one-click procedural scene generators. These presets serve as instant learning templates, interactive playgrounds, and production starting points.

How to Use the Generator
------------------------

1. Open the **Reactive Surface FX** tab in the 3D Viewport sidebar (:kbd:`N` panel).
2. Scroll to the **Demo Setups** panel.
3. Select your desired setup from the **Preset Demo Setups** dropdown.
4. **Replace Existing in Scene**: Check this option if you want to cleanly clear an existing demo setup before creating a new one.
5. Click **Add Demo Setup**.
6. Press :kbd:`Spacebar` to play the animation and watch the demo run in real time!
