Displacement Materials
The vortex materials use procedural noise shaders to deform mesh vertices in real-time, creating the swirling, organic surface of the tunnel. All parameters are exposed on material instances for easy tweaking.
Material Parameters
| Parameter | Description |
|---|---|
| Noise Scale | Size of the displacement pattern |
| Displacement Amount | How far vertices are pushed outward |
| Animation Speed | How fast the noise animates |
| Color Scheme | Base colours and gradients applied to the surface |
| Emissive Intensity | Glow strength for the tunnel walls |
| Noise Type | Switch between different procedural noise algorithms |
Material Blending Along the Path
You can blend different material instances across zones of the spline:
- Define blend zones in the Vortex Data asset
- Assign a different material instance to each zone
- Set the blend transition distance
- Materials interpolate smoothly between zones
💡 Creating custom materials: Duplicate a provided material instance, adjust its displacement and colour parameters, and assign it to your VortexTunnel actor.
