Point Renderer

Flat discs, or sprite-sheet cells when a sheet is wired, with softness, shadows, echo trails, and four colour modes.

The Point Renderer draws each particle as a flat disc facing the camera. It is the cheapest renderer and the one to start with.

Point Renderer

  • Point / Sprite Size, Softness, Color Mode
  • A wired Sprite Sheet turns the discs into cells
  • Echo smears the frame; for real ribbons use the Trail Renderer
  • Found in the node graph under Particles → Renderers
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 sphere emitter with a curl effector, drawn as default discs.

Parameters

Point Renderer parameters
  • Opacity (0–1, default 1), Point / Sprite Size (1–100, default 10), Size Random (0–1, default 0.6).
  • Color Mode — Single (default), Gradient, Emitter Image, or Colorize Effector; Color (default #b8b8b8).
  • Gradient By and Gradient Cycles (default 1) for the Gradient mode, with Edge Softness.
  • Additive (default off), Echo (default off) with Echo Decay (0.5–0.99, default 0.9).
  • Shadows (default off), Shadow Strength (default 0.6), Shadow Bias.
  • Softness (0–1, default 0) — feathers the disc edge.
  • Particle Use Amount (0–1, default 1) — the share of particles this renderer draws.
  • Shadow Mode — Depth Map (default) or Volumetric, with Absorption (0–8, default 1) and Shadow Steps (1–32, default 12).

Sprite sheet

  • Sheet Columns and Sheet Rows (1–32, default 1), Animation FPS (0–60, default 12), Playback (Loop default, Ping-Pong, Play Once (Life), Random Cell), Random Start Frame, Frame Offset, Rotation Random.

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

Examples

Soft fog — Softness 1, Additive on, Opacity 0.3.

Troubleshooting

Colorize Effector has no effect — set Color Mode to Colorize Effector.
