Epic Games releases official Blender to Unreal Engine tools
Wednesday, July 15, 2020 | Written by Jim Thacker
Epic Games has released Send to Unreal and UE to Rigify, its plugins for transferring manipulated and animated characters between Blender and Unreal Engine.
The tools that have been under development for several months – the video above comes from a preview livestream in February – are intended to optimize the workflow for game development in Blender.
Transfer character animations with one click between Blender and UE4 – if your scene scale is right
The add-ons offer a one-click transfer workflow that automatically converts Blender characters for use with UE4s standard mannequin and UE4 rigs for use with Blenders Rigify add-on for automatic rigging.
However, both currently have the same limitation as Blender's standard FBX exporter: these assets must be created with a Blender unit scale of 0.01 for bone scaling to work properly in UE4.
This can lead to workflow problems in Blender, which are discussed in more detail in this forum post.
As an alternative, many game artists rely on the third-party Mr Mannequins Tools add-on, which is available for a fee and automates scaling conversion.
In a Reddit thread, Jim Kroovy, author of Mannequins Tools, commented that he would continue to develop the plugin, but that he "wanted to send to Unreal to be the export add-on for Blender to UE4".
Availability and system requirements
Send to Unreal and Unreal to Rigify are available under the EULA of the Unreal Engine. Both can be downloaded for free. The plugins are compatible with Blender 2.83+ and Unreal Engine 4.25+.
