Getting started
- Getting Started Install the plugin, activate your license and send your first prompt. About 10 minutes from download to your first Blueprint.
- Interface Tour A map of the CoPilot panel: the rail of screens, the chat list, the composer and the footer strip.
- Best Practices Cheatsheet How to get better results from the AI, faster: context, phrasing, modes, model choice and the settings worth knowing. License required
- AI Providers Pick the AI behind the CoPilot: BpLabs Standard, your own API key, a local model or a coding agent. Up to nine slots, switchable per chat. License required
- Tokens and BpLabs Premium How tokens work for our hosted models and hosted generation, how to buy packs, and when BpLabs Premium is worth it. License required
- Account, License and Devices Activating the plugin, the Account screen, moving to a new computer, switching licenses and what the plugin sends to our servers.
Core features
- Architect The main AI chat. Four interaction modes, attachments, @ mentions, a review step for every Blueprint it changes, and confirm prompts before anything destructive. License required
- Crew Split a big build into checkpoints. A worker builds each one, a reviewer checks it against your success criteria, and failed checkpoints retry on their own. License required
- Project Index and Dashboard Scan your project once so the AI can find any asset by name or purpose. Then explore dependencies, complexity and performance on the Dashboard. License required
- AI Agents Run Claude Code, Codex, Gemini CLI, GitHub Copilot and dozens of other coding agents inside the editor, on your own subscription, with every CoPilot tool. License required
- Tool Categories Every area the AI can work in. 1,655 tools: core categories that are always there, plus 37 extensions, 15 of them on by default. License required
- Asset Generation Generate 3D models, textures, images, sound and video. From the chat, from Cloud Studio on paid providers, or from Local Studio on your own GPU. License required
- Tools Screen Four standalone utilities: split a skeletal mesh at bones, merge modular meshes, retarget animations between skeletons, and profile performance. License required
- Source Control Commit, sync, shelve and branch from one screen with Git, Perforce or Diversion. The AI uses the same backend, and asks before every change by default. License required
Advanced
- Voice Talk to the Architect instead of typing. Speech-to-text in the cloud or fully offline on your PC, plus replies read aloud. License required
- Notifications Get a Discord or Slack message when a long task finishes, or when the AI stops to wait for your answer. License required
- MCP Integration Drive your editor from Claude Desktop, Claude Code, Cursor or any MCP client. And plug other MCP servers into the CoPilot. License required
- Local LLM Setup Run the CoPilot on a model on your own PC with Ollama or LM Studio. No key, no cost per message, nothing leaves your machine. License required
- AI Memory What the AI remembers about your project across every chat. See it, edit it, switch entries off, or teach it something on purpose. License required
- Game Design Docs Give the AI your game design docs. It searches them when it needs to, helps you write one from scratch, and turns one into a build plan. License required
- Extensions 37 tool packs you switch on and off. 15 are on by default. Turn on the rest when your project uses Mover, Water, MetaHuman, Steam and more. License required
- Logic Driver Pro Build Logic Driver Pro state machines by asking: states, transitions, conduits, condition graphs, layout and a PIE check, through Logic Driver Assist.
- PaperZD Build 2D character animation in PaperZD by asking: flipbooks from a sprite sheet, animation sources, Animation Blueprints, state machines, playable characters and a play check.
- Voxel Plugin Build procedural terrain in Voxel Plugin 2 by asking: rolling hills, mountains, caves, floating islands, painted surfaces, scattered trees and blocky Minecraft-style worlds.
- Blueprint to C++ Turn a Blueprint into a C++ class that compiles. The Blueprint stays untouched, and anything that can't be translated is marked for you. License required
- Play Testing Let the AI play your level to check its own work. It starts Play In Editor, drives input, looks at the frames and reports pass or fail. Experimental. License required
- Editor Control The AI drives the whole Unreal Editor like a person at the keyboard: any panel, any window, any plugin's UI. It runs multi-step workflows, repeats them across your project, and records them for replay. License required
Learning and reference
- Learn Courses inside the editor that teach the plugin and Unreal basics. Lessons can complete themselves when you do the step for real. License required
- Settings Every Settings page explained: AI Models, Image & 3D, Audio, Appearance, Accessibility, Preferences, AI Behaviour, Project Index, Extensions and Info. License required
- Supported Languages The plugin speaks 20 languages, and you can prompt the AI in any of them. Think in your language, create in Unreal.
- Frequently Asked Questions Common questions about pricing and plans, AI providers, privacy, engine versions, licensing and your data.
- Changelog Version history and release notes for Ultimate Engine CoPilot.
- Features overview A tour of everything the plugin can do.
