Logo Uiana - VALORANT Map Importer

Uiana is an Unreal Engine 5 editor plugin for importing VALORANT game maps. It extracts map data from VALORANT's PAK files and imports them into Unreal Engine with materials, meshes, lighting, and decals. Heavily inspired by Piana by Luviana.

Features

  • Import VALORANT maps directly into Unreal Engine 5
  • Automatic extraction of meshes, materials, textures, and decals
  • Support for sublevels and lighting import
  • Built-in CUE4Parse integration for asset extraction
  • UEFormat support for mesh assets (.uemodel)

Requirements

Before installing the plugin, ensure you have the following:

Installation

1. Download the Plugin

  1. Download the latest release
  2. Extract the ZIP file

2. Install Dependencies

Install the UEFormat plugin:

  1. Clone the UEFormat repository and switch to the unreal branch
  2. Copy the inner UEFormat folder (containing UEFormat.uplugin) to your project's Plugins folder
  3. Alternatively, clone this repo with submodules: git clone --recurse-submodules and copy UEFormat/UEFormat to your project's Plugins folder

3. Install Uiana Plugin

  1. Create a Plugins folder in your Unreal Engine project root (if it doesn't exist)
  2. Copy the Uiana folder from the downloaded ZIP into your project's Plugins folder
  3. Important: Install in your project's Plugins folder, NOT the Engine Plugins folder
  4. Rebuild your project in Visual Studio if prompted

4. Verify Installation

  1. Open your Unreal Engine project
  2. Look for the Uiana icon in the toolbar at the top of the editor
  3. Click the icon to open the Uiana import window
