Changelog

Releases are listed newest first. Each entry covers what shipped in that version of the plugin, new domains, panel features, behavior changes, and breaking changes when they happen.

Unreleased

A large wave of new asset domains and editor tooling on top of the v1.0 surface — each one with the same validated-JSON, auto-layout, and full-test treatment.

New asset & gameplay domains

• Gameplay Ability System (gas): ability / effect / cue Blueprints, attribute sets, and the gameplay-tag registry.
• Data Tables & Data Assets (data): row CRUD, search / sort / batch, CSV + JSON import-export, composite tables with override / conflict inspection, and fully structured Data Asset values.
• IK Rigs & Retargeting (ik) and Pose Search / Motion Matching (pose_search): solvers, goals, retarget chains, schemas, databases, and interaction assets.
• Chooser Tables (chooser): data-driven selection tables and proxy-table indirection.
• Textures (texture): render targets, collections, sub-UV and media textures, plus property tuning on any texture.
• Physics (physics + physical_material): collision channels / profiles, physics settings, the physical-surface registry, and physical-material assets.
• Landscape, Groom & Hair, Paper2D, Fonts, and Touch Interfaces.

Deeper graph & stack authoring

• Niagara emitter-stack modules and script graphs, PCG graphs, Cinematics / Sequencer (bindings, tracks, keyframes, camera cuts, sub-sequences), and Gameplay Cameras (variable collections, camera assets, rigs, shakes) — all with node search and auto-layout. Materials, Audio, and Meshes gained full graph / family coverage too.

World Partition & Levels

• Per-level World Settings + GameMode override, World Partition Data Layers, runtime-grid configuration and streaming toggles, and the editor Levels-window state (current level, visibility, lock, lighting scenario, move-actors-between-levels) — each returning actionable diagnostics when a World Partition map isn’t open.

Profiling & debugging tooling

• Profiling (profiling): Unreal Insights trace capture + headless TraceServices analysis (frame stats, percentiles, bottleneck timers, counters), the CSV profiler, and a one-shot live perf snapshot.
• Debugging (debug): console / cvar / log-verbosity control, the Visual Logger (record + headless analysis), and replay / gameplay-debugger / debug-draw / audio-debug / Chaos Visual Debugger tooling, each gated per tool.

v1.0: Initial release

The first public version of Blueprint AI ships with the full surface described in the rest of these docs.

Editor operations

• The initial asset-authoring surface, covered end-to-end: Blueprints, Animation Blueprints, Behavior Trees, State Trees, Enhanced Input, Control Rig, UMG Widget Blueprints, Common UI, Curves, Environment Queries, Static / Skeletal Meshes, Materials, Niagara, Sound, and MetaSound.
• Validated JSON operations: every change goes through the engine’s own schemas before any Python runs, so what lands in the Content Browser compiles cleanly.
• Auto-layout on every graph mutation: deterministic six-phase algorithm, reroute knots for long wires, pure-getter dedup. No spaghetti graphs after an AI edit.
• Declarative specs for higher-level assets (Behavior Trees, State Trees, Animation state machines), the AI describes the structure once and Blueprint AI decomposes it into the underlying ops.

AI assistant integration

• Auto-installed skill files for five assistants on first editor launch: Claude, Cursor, GitHub Copilot, Windsurf, Codex.
• Bundled in-editor chat panel (Claude), dockable tab with chat, embedded terminal, attachments, slash commands, @-mentions, and a live context-usage ring.
• Bring-your-own path via the self-documenting CLI for any other assistant that can shell out.

Panel & sessions

• Embedded terminal backed by xterm.js + ConPTY / POSIX PTY, ANSI colors, scrollback, native shell history, curses-app compatible.
• Session store as plain JSONL on disk with a file-watcher-backed Session Drawer, search across titles / content / tool names, and time-grouped history.
• Replay engine restores message bubbles, tool-use status, attachments, mode, and context-ring state when switching sessions.
• Five attachment types: files, images, viewport captures, editor selection, folder snapshots, with picker, drag-and-drop, paste, and live-selection toggle entry points.
• Multi-account login with a credentials locker at ~/.claude/BlueprintAI/<email>/ for fast switching.

Headless & CI

• Editor-not-required operation: every op runs through a short-lived Unreal commandlet. Drive Blueprint AI from your IDE, terminal, or CI pipeline without an open editor.
• cli.py validate for engine-free type-checks on every push.

Configuration

• CSS-flavored theming via JSON stylesheet at Resources/Theme/, hot-reloads on save, no editor restart.
• 23-culture localization (English + 22 translations) covering the panel UI and Editor Preferences. Editor language is honored automatically.
• Settings split between developer-local Editor Preferences and team-shared Project Settings.
• Privacy-first telemetry, opt-in only, anonymous error reports via Sentry, no source code / chat / asset content ever leaves the machine.
• Project conventions layered on top of bundled defaults via CLAUDE.md / AGENTS.md at the project root.

Known limitations

• The bundled chat panel is currently Claude-only. Cursor, Copilot, Windsurf, and Codex get the skill auto-installed for them but drive Blueprint AI from their own UI today; bringing them into the panel’s Agent dropdown directly is on the roadmap.
• A handful of operations need a live editor (some PIE-specific assets, certain Niagara workflows). The CLI detects these and prints a clear “this op needs an open editor” diagnostic instead of failing silently.
