Emitter settings open on the right with spawn amount, emitter lifetime and spawn shape fields, while a heart burst plays in the viewport — Emitter settings: spawn amount, lifetime and shape, each field with its source path.

01 · EDITING

Every setting as a form field

Emitter rate, lifetime and shape. Motion, rotation and collision. Appearance, color, texture and UV. Particle lifetime, kill plane, block expiry lists and Molang variables.

Sliders, drag-the-number editing, exact numbers, or Molang in any numeric field.
A question-mark button on every field shows its description, source path and current value. 94 settings fields are documented.
Undo and Redo on everything, including gizmo drags, texture edits, Library metadata and AI edits. Reset any field or group to its imported value.
Quick Setup presets for shape, timing, physics and seven sprites.
Imports particle JSON and Snowstorm files and keeps unknown fields and formatting byte for byte. Exports Bedrock JSON.
Autosave every 5 to 10 minutes with up to ten rolling recovery snapshots.
Dockable panels and named layouts. Undock the bottom panel, Cyber AI or the viewport to its own window.

02 · VIEWPORT

A live preview that follows Bedrock's rules

Additive, blend, alpha-test and opaque materials render with Bedrock's depth and blend rules.

Gizmos write real particle data: aim the emitter, drag motion arms for velocity and acceleration, move a particle and the app re-solves its start velocity, size and spin.
Ghost preview of an edit before it commits.
Skybox, ground grid, collision preview, screenshots and WebM recording of the viewport.
Vibrant Visuals preview with emissive bloom and a time-of-day sky, an approximation calibrated against in-game captures.

04 · EVENTS AND TIME

TreeLine, TimeLine and PerformanceLine

TreeLine

An event graph with sequence and randomize branches, child effects and sounds, and creation, expiration, timeline, travel-distance and collision triggers. The event inspector renames events and updates every reference. Validate event graph reports missing references and bad weights.

TimeLine

Layers, keyframes, snap and zoom, with a curve editor for linear, catmull_rom, bezier and bezier chain curves. Split or joined handles, safe delete with reference replacement, and Bind curve to particle field.

PerformanceLine

Measured particle and emitter counts, root event calls, frame interval, FPS and preview CPU per frame, tick or second. Jump the playhead to a spike, export to JSON, or Fix with Axe. It reports measurements only, with no scores or budgets.

TreeLine open under the viewport with the olctd:cloud_a event selected and the event inspector showing name, time, trigger occurrence, weight and children — TreeLine with the event inspector open on the right.
