How to setup Blender for use with Unreal

Install PROTO Game Asset Tools (Add-On)

Blender's default FBX Exporter has problems with Unreal. It is highly recommended to use this add-on

This add-on is by the author of kemorig, and is designed for working with Unreal. It exports FBX files properly for Unreal, and comes with extra goodies for improving Blender’s character workflow.

Blender Extensions

If you need help installing this extension, see this guide.

Set Length Units to Centimeters (Optional)

In Unreal, 1 unit equals 1 centimeter. It’s convenient to also use centimeters in our scene.

In Blender, on the right side of the screen, find Scene Properties > Units and set Length to Centimeters.

Do not adjust the Unit Scale parameter, which is 1.0 by default. Some outdated online tutorials recommend adjusting it for Unreal. Do not do this.

Scene settings are saved per .blend file. You will need to make this adjustment each time you make a new file in Blender.

Other Blender Add-Ons
