Installation

RetroRender ships as a RetroRender plugin folder containing one editor module (RetroRenderEditor) and the plugin content (material functions, post-process, masters, presets) under the /RetroRender mount point.

Requirements

Requirement	Detail
Engine version	Unreal Engine 5.2 → 5.8
Project type	C++ or Blueprint-only (a prebuilt binary is included)
Platform	Windows editor
Dependency	QuadricMeshReduction plugin (bundled with the engine, enabled by default) — required by the Decimate Baker

From Fab

1. Add RetroRender to your account on Fab.
2. In the Epic Games Launcher → Unreal Engine → Library → Fab Library, find RetroRender and click Install to Engine.
3. The plugin is now available to every project on that engine version.

Manual installation (into a single project)

1. Copy the RetroRender folder into your project's Plugins/ directory:

   <YourProject>/Plugins/RetroRender/

2. Restart the editor. When prompted to rebuild missing modules, click Yes (only required for source/C++ projects).

Enable the plugin

1. Edit → Plugins.
2. Search for RetroRender (Category: Rendering).
3. Tick Enabled and restart the editor if prompted.

tip

The Decimate Baker relies on the engine's mesh-reduction backend. If baking reports "no mesh-reduction backend available", enable QuadricMeshReduction under Edit → Plugins → Editor and restart.

Verify the install

Open Tools → RetroRender. A dockable panel with three tabs (Bake, Textures, Look) should appear. If it does, you are ready — head to Getting Started.
