Ramp

Ramp in Cinema 4D Redshift is a powerful gradient mapping node used to remap input values—like noise, curvature, or custom data—into color transitions or mask values. This gives artists control over shading transitions, contrast, and procedural effects directly inside the Redshift Material Graph.

What It Is

• Gradient remapping node that converts grayscale input into color or value ramps.
• Offers multiple interpolation modes: Linear, Smooth, Constant, and Step.
• Used to stylize shading, limit effects, or create procedural transitions.

How It Works

1. Add the Ramp node: Inside the Redshift Shader Graph, create a Ramp node and connect it to a scalar or RGB input like noise or curvature.
2. Edit gradient stops: Define color points and adjust their position and interpolation type for precision control.
3. Use in shaders: Feed the output into parameters like Base Color, Roughness, or Emission for visually-driven effects.

Use Cases

• Masking effects: Isolate areas using noise and ramp contrast to apply wear, dirt, or emission glow.
• Gradient transitions: Create stylized shading based on curvature or ambient occlusion.
• Control variation: Procedurally shift colors across instances or clones for organic or data-driven results.

Benefits

• Precise gradient control inside Redshift without external textures
• Highly flexible for procedural shading and MoGraph workflows
• Optimized for performance with GPU-accelerated rendering
• Useful in both technical and artistic material creation pipelines
