## What it does

The skill covers playing Level Sequences from C++ and building cutscenes. It walks through the `MovieScene`, `MovieSceneTracks`, `LevelSequence` and `CinematicCamera` modules, a runtime-versus-editor table, and code samples for `CreateLevelSequencePlayer`, `SetBindingByTag` and event tracks.

Offline rendering gets its own section. The `MovieRenderPipeline` plugin is disabled by default, so you enable it in the `.uproject` and add `MovieRenderPipelineCore` to `Build.cs`. Skip that and the render code will not compile. The skill also reads `.agents/ue-project-context.md` when the file exists and carries on when it does not.

Target engine is UE 5.8, with APIs checked against the 5.8 headers and older forms listed separately as deprecated. Neighbouring topics stay out: animation tracks live in `ue-animation-system`, gameplay cameras and shakes in `ue-gameplay-cameras`, sequence audio in `ue-audio-system`.

## Requirements
- Works with: Unreal Engine

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add quodsoler/unreal-engine-skills --skill ue-sequencer-cinematics -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/ue-sequencer-cinematics/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/ue-sequencer-cinematics/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add quodsoler/unreal-engine-skills --skill ue-sequencer-cinematics -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/ue-sequencer-cinematics/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add quodsoler/unreal-engine-skills --skill ue-sequencer-cinematics -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/ue-sequencer-cinematics/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install quodsoler/unreal-engine-skills ue-sequencer-cinematics
```

2. **Manually: put the files in place**
- File: `.github/skills/ue-sequencer-cinematics/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add quodsoler/unreal-engine-skills --skill ue-sequencer-cinematics -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/quodsoler/unreal-engine-skills --path skills/ue-sequencer-cinematics
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/ue-sequencer-cinematics/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add quodsoler/unreal-engine-skills --skill ue-sequencer-cinematics -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/quodsoler/unreal-engine-skills/tree/HEAD/skills/ue-sequencer-cinematics/SKILL.md

## When to use it
- play a cutscene from C++ without the player and actor getting garbage collected
- rebind sequence tracks to actors that only exist at runtime
- fire C++ from a key on the timeline with an event track
- tell which Sequencer calls are safe in a shipped build and which mutate the asset
- enable Movie Render Queue and write frames to disk

## Example prompts
- Show me how to spawn a ULevelSequencePlayer from C++ and play a cutscene
- How do I bind actors to Level Sequence tracks at runtime with SetBindingByTag?
- Set up sequence rendering through Movie Render Graph

# UE Sequencer and Cinematics

Target engine: **UE 5.8**. APIs below are verified against the 5.8 headers; older forms are listed under "Deprecated — do not use".

Sequencer spans three runtime modules plus a plugin. `MovieScene` holds the data model and the player base class, `MovieSceneTracks` holds the concrete track and section types, `LevelSequence` holds the asset, actor, player and director, and `CinematicCamera` holds the cine camera and camera rigs. Offline rendering lives in the **Movie Render Queue** plugin (`MovieRenderPipelineCore` for runtime, `MovieRenderPipelineEditor` for the editor queue UI); it is disabled by default and must be enabled in the `.uproject`.

## Context

Read `.agents/ue-project-context.md` if it exists (module names, conventions, enabled plugins, GAS/networking setup). Do not stop if it is missing.

Identify the area from the request and the codebase. Ask only when two plausible readings would produce different code.

| Request is about… | Go to |
|---|---|
| Which modules to add to Build.cs | [Build.cs Modules](#buildcs-modules) |
| What C++ can do at runtime vs editor-only | [Runtime vs Editor](#runtime-vs-editor) |
| Starting, stopping, seeking, looping a sequence | [Playing a Level Sequence](#playing-a-level-sequence) |
| Pointing sequence tracks at gameplay actors | [Binding Actors at Runtime](#binding-actors-at-runtime) |
| Calling C++ from a key on the timeline | [Sequencer Event Tracks](#sequencer-event-tracks) |
| Tracks, sections, sub-sequences, frame math | [MovieScene Data Model](#moviescene-data-model) |
| Cine camera setup, focus, rails and cranes | [Cine Cameras and Camera Rigs](#cine-cameras-and-camera-rigs) |
```
