Gradient

The Gradient node draws a directional color gradient across the frame. Set the angle, the color stops, and how the ramp repeats — useful as a background, a color source, or a value ramp to drive other operators.

• One texture output; two optional texture inputs (domain warp and composite)
• Angle, interpolation, repeat, mirror, offset, and width controls
• Colors are set in an inline gradient editor in the parameters panel
• Found in nerdGRAPH under Generators as Gradient

The image on the right is the example patch itself — drag and drop it onto the app (or load it with File → Load) to open the full graph.

Inputs and outputs

Parameters

Opacity, Blend Mode — the standard operator header; see Perlin Noise.

Colors

The gradient's colors live in the inline gradient editor in the parameters panel. It seeds a rainbow the first time you select the node; click a stop to recolor it, or double-click the bar to add stops.

Shape

• Angle (0–360, default 0) — the direction of the ramp.
• Interpolation — Linear, Smooth, Cosine, or Stepped transitions between stops.
• Repeat (0.5–20, default 1) — how many times the ramp tiles across the frame.
• Mirror — reflect each repeat so the ramp ping-pongs instead of hard-resetting.
• Offset (−1 to 1) — slide the ramp along its direction.
• Gradient Width (0.1–10, default 1) — stretch or compress the ramp within each repeat.

Transform

• Seed and the shared Scale / Offset / Rotation block.

Every slider has a per-parameter animation bar, so any of these can be animated, audio-driven, or MIDI-mapped — see Parameters and Controls.

Troubleshooting

Ramp looks banded — set Interpolation to Smooth or Cosine; Stepped is intentionally hard-edged.

Only part of the ramp shows — lower Repeat and set Gradient Width to 1 to fit one full ramp across the frame.
