A visual slice-to-LED editor for Unreal Engine. Design your LED wall or volume mapping directly in-editor and generate the assets you need for either of two complete workflows — no external tools, no round-trips.
Think of it like a Resolume-style pixel-map editor that lives inside Unreal's asset system and speaks nDisplay + post-process materials.
This repository is the public home for LED Mapper's documentation, release notes, and issue tracker. The plugin itself is distributed through the Fab marketplace (the repo has no code).

- Supported engine: Unreal Engine 5.7+, Windows
Start here if you're new:
- Concepts — layout assets, screens, slices, and the two workflows
- 3D mesh workflow — nDisplay / in-camera VFX
- 2D pixel-remap workflow — post-process camera compositing
- Keyboard & mouse reference — all the shortcuts
- Troubleshooting — precision, TAA, camera mismatch, focus, and other gotchas
| 3D mesh workflow | 2D pixel-remap workflow | |
|---|---|---|
| Use when | Driving real LED panels via nDisplay, or ICVFX captures where the virtual camera should see the LED content | Remapping a CineCamera's output onto an LED processor pixelmap (post-process compositing) |
| You design | Where pixelmap slices sit on physical panels in the world | What part of the camera image feeds each chunk of the LED pixelmap |
| You generate | Static meshes sized to real panel dimensions + unlit material instance per screen | FP32 UV-remap texture + pre-wired post-process material per screen |
| You then | Drop meshes in your world, drive them with nDisplay or a scene capture | Plug the material onto a camera / SceneCapture as a blendable |
Both workflows share the same editor, the same asset, and the same canvas. You just pick which mode at asset-creation time.
