Blender IO Datasmith

This repo contains a Blender add-on to import and export Epic Games Datasmith format from Blender, and a corresponding plugin for Unreal Engine to support some features that Blender can export into the Datasmith format.

Features

• Scene hierarchy
• Meshes
• Textures
• Materials and node graphs
• Instanced meshes
• Lights and cameras
• Object transform animations

Installation

Check for the latest version in the Releases section in Github. You can download packaged zip files for the Blender add-on and the Unreal Engine plugin.

To install the Blender add-on, you can download and add it to Blender through the preferences window. Alternatively you can download the repo and add the root of it as a source of scripts within Blender preferences. This way is recommended for development to make it easier to work on the add-on.

The Unreal Engine plugin should be downloaded for the relevant version and placed in the Plugins folder of your project. You can also place it in the UE Engine folder, but this is not widely tested.

Usage

To use the plugin, just browse in the Blender import/export menus and select the Datasmith format.

IMPORTANT: From Unreal, you can import the datasmith file normally, but you need to fix the blender_curves asset to NOT use compression. You can do this in to ways:

• Find the file in the Textures folder that was created when importing the files. Edit the texture type to use HDR uncompressed.
• Use the Dataprep asset included in the plugin folder.
