[v3.1.0] - 2026-06-01 - The one with particles improvements
Added
Particle Playground timeline editing now supports emitter visibility, grouped clip/keyframe moves, and scratch-composite undo/redo.
Added Texture Lab for procedural particle sprites, masks, noise, gradients, spline paths, and shape/polygon textures.
Texture Lab can send generated PNGs to Particle Playground emitters and Shader Graph texture slots.
Texture Lab supports saved recipes, solid/background color controls, generator-specific resets, spline overlap modes, and direct spline/shape editing.
Texture Lab dimensions now include 4 x 4, 8 x 8, 16 x 16, and custom width/height outputs.
Texture Lab atlas authoring now includes editable frames, seeded fills, onion skinning, uploaded-frame replacement, ZIP export, Particle Playground atlas metadata, and safe all-frame actions.
Added persisted local creative sessions for game-free Shader Graph, Particle Playground, and Texture Lab workspaces.
Changed
Texture Lab now keeps Comet Tail and Slash as Spline Trail path presets instead of redundant hardcoded generators.
Fixed
Fixed Shader Graph embedded previews for Fake 3D and other derivative-based nodes so Preview nodes/showcase previews match the game runtime instead of falling back silently.
Fixed Texture Lab Shapes & Polygons so Spline layers can be edited in the preview point editor.
Fixed Texture Lab generator and spline preset switching so each preset restores its default controls instead of inheriting stale values from the previous recipe.
Fixed Particle Playground timeline drags so focused numeric clip editors cannot write stale values back over direct clip movement.
Fixed local Particle Playground previews so web and creative-session playback follow authored timeline timing.
Fixed CLI watch startup so immediate Android/iOS file edits are not missed while the native watcher settles.
Tests
Added focused Shader Graph coverage for WebGL preview derivative support.
Added focused/Lua/app/showcase coverage for Particle Playground timeline grouping, undo/redo, atlas metadata, and export paths.
Added app/showcase coverage for local Particle Playground preview timeline playback.
Added focused Texture Lab dimension coverage alongside app/showcase coverage for generators, recipes, spline/shape editing, atlas workflows, layout, and confirmation dialogs.
Added focused/app coverage for creative session persistence and local creative-tool access without runtime commands.
