Colorize Effector

Tints each particle from a gradient driven by an attribute such as life, position, or density.

The Colorize Effector assigns colour by an attribute. A wired Gradient texture replaces the built-in stop editor.

Colorize Effector

  • Attribute picks what drives the ramp
  • Cycles, Ramp Offset, Wrap, Blend Mode, Color Blend
  • Found in the node graph under Particles → Effectors
Example patch — drag onto the app to load

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. A Gradient generator wired into the Gradient port.

Inputs and outputs

Colorize Effector node

PortTypePurpose
Effectors InEffectorThe previous effector in the chain, if any.
GradientTextureOverrides the built-in gradient.
Field ImageTextureA texture read by the Image field shape.
Origin ObjectSurfaceA Null to parent the effector to.
Effectors OutEffectorWire it into the next effector, or into the Particle System's Effectors port.

Parameters

Colorize Effector parameters
  • Attribute — Position X / Y / Z, Normal, Life (default), Distance from Emitted Position, Distance from Origin, Density. Density Multiplier and Density Contrast shape the Density option.
  • Cycles (0.1–32, default 1), Ramp Offset (0–1, default 0), Wrap (Repeat, Clamp default, Mirror).
  • Blend Mode — Replace (crossfade) (default), Multiply, Add. Color Blend (0–1, default 1).
  • Interpolation — Linear (default), Smooth, Step.

Field

  • Field (default off) — limits the effector to a region. Field Shape (Sphere, Box, Plane, Image), Field Size (default 3), Falloff (default 0.5), Inner Radius, Invert Field, Field Follows Mouse, and Image Channel for the Image shape. The Field Position / Heading / Pitch / Roll / Scale block places it.

Cycles, Ramp Offset, and Color Blend carry a per-parameter animation bar.

Examples

Heat map — Attribute Density, a red-to-white gradient.

Troubleshooting

Nothing changes colour. The renderer's Color Mode must be set to Colorize Effector. The Mesh Renderer takes colour from its material instead.
