Image Form Effector

Particles climb the image's brightness and settle on bright areas, forming the picture.

The Image Form Effector pulls an existing cloud into the shape of a picture.

Image Form Effector

  • Strength, Plane Size, Flatten To Plane
  • Match Image Emitter aligns with an Image Emitter's plane
  • 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 Plasma generator wired into the Image port.

Inputs and outputs

Image Form Effector node

PortTypePurpose
Effectors InEffectorThe previous effector in the chain, if any.
ImageTextureThe picture to form.
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

Image Form Effector parameters
  • Strength (0–200, default 20).
  • Plane Size (0.5–50, default 10).
  • Match Image Emitter (default off) — use the same plane as an Image Emitter in the chain.
  • Flatten To Plane (0–20, default 2) — pulls particles onto the plane in Z.
  • Particle Use Amount (0–1, default 1) — the share of particles this effector acts on. Two effectors with the same amount act on different particles.
  • Speed Variance (0–4, default 0) and Speed Bias (−1 to 1, default 0) — scatter the force per particle.

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.

Every slider has a per-parameter animation bar, so it can be animated, audio driven, or MIDI mapped.

Examples

Logo assembly — a Text generator into Image, a Drag Effector after this.

Troubleshooting

Nothing moves. The effector's Effectors Out must reach the Particle System's Effectors port, directly or through the last effector in a chain.

The picture is fuzzy — raise Flatten To Plane and add drag.
