RiftbornAI

An AI game director
inside Unreal Engine 5.7.

Describe a scene in plain English. RiftbornAI builds it inside your live editor — terrain, lighting, blueprints, characters, foliage, cinematics. Native C++ panel, ~500 tools, vision-loop verification.

A forest environment built entirely from natural-language prompts inside the UE editor.

What it does.

You type. The plugin plans. It calls real editor APIs. It screenshots the viewport. It iterates until the result matches the intent. Nothing leaves your machine unless you bring your own LLM key — and even then, you can run everything locally with Ollama.

Environments

Landscape sculpt, multi-layer materials, weight-painted foliage, atmospheric fog, water bodies, post-process volumes.

Lighting

Directional, point, spot, rect lights. Sky atmosphere. Vision-loop verifies mood against the prompt.

Blueprints & gameplay

Blueprint creation, component wiring, characters, navigation, AI perception, GAS abilities.

Materials & PCG

PBR graphs from texture maps, parameter-driven instances, landscape blends, PCG graphs, Niagara systems.

Cinematics

Level Sequences, camera animation, keyframing, playback control.

Community-extensible

Stable IToolModule SDK. Ship your own tools as a sibling .uplugin. Reference example in the repo.

How it fits into your pipeline.

RiftbornAI is two things at once. A native C++/Slate copilot panel that docks inside the Unreal editor like any other tab — chat, plans, approvals, tool browser, execution history. And an MCP server that the installer wires into Claude Desktop, VS Code, Cursor, and Windsurf, so the same ~500 tools show up there too.

Bring your own LLM key — Anthropic, OpenAI, Google, or a local Ollama install. No subscription, no per-seat cost, no telemetry unless you explicitly turn it on. Every mutating tool runs through a governance pipeline with risk tiers, undo strategies, confirmation tokens, and cryptographic proof bundles you can audit.

Free during beta. Pay once at v1.0.

RiftbornAI is free while it's in beta — download, install, use it in your games. No DRM, no expiry, no nag. When we cut v1.0 stable, the plugin becomes paid. Founding Supporters who buy now lock in the v1.0 price and get lifetime updates.
