Legacy/Blender Legacy/Character from Blender to UE4 Legacy/Exporting the Mannequin Skeleton from Unreal Engine 4 to Blender and Re-importing. Blender is getting more powerful by the day, and to improve the Blender to Unreal Engine workflow we're developing a 'Send to Unreal' add-on for Blender. Unreal Engine 4 is ranked 4th while Blender is ranked 7th. The most important reason people chose Unreal Engine 4 is: The engine, including full access to source code, is free to use; a 5% royalty is due only when you monetize your game or other interactive off-the-shelf product and your gross revenues from that product exceed $1,000,000 USD. Hadrien; November 10, 2020; Fantastic! This plan washes away most of the worries I had when I first heard “pebbles scattering”. This plan covers a lot of use cases, and different data types as well (moss as hair, tree bark as geometry, campfire as a volume, snails as dynamic particles, pebbles as static particles).

Epic Games has released Send to Unreal and UE to Rigify, its plugins for transferring rigged and animated characters between Blender and Unreal Engine.

The tools, which have been in development for several months – the video above is from a preview livestream this February – are intended to streamline game development workflow in Blender.

Transfer character animations between Blender and UE4 in one click – if your scene scale is right
The add-ons provide a one-click transfer workflow, automatically converting Blender characters for use with UE4’s default Mannequin, and UE4 rigs for use with Blender’s Rigify auto-rigging add-on.

However, both currently have the same limitation as Blender’s standard FBX exporter: that assets must be created using a Blender Unit Scale of 0.01 in order for bone scaling to work correctly in UE4.

That can cause workflow issues within Blender, discussed in more detail in this forum post.

As an alternative, many games artists rely on third-party add-on Mr Mannequins Tools, which is available on a pay-what-you-want basis, and which automates the scale conversion.

In a Reddit thread, Mr Mannequins Tools author Jim Kroovy commented that he will still continue to develop the plugin, but that he “want[s] Send to Unreal to be THE Blender to UE4 export add-on”.

Availability and system requirements
Send to Unreal and Unreal to Rigify are available under the Unreal Engine EULA. Both are free to download. The plugins are compatible with Blender 2.83+ and Unreal Engine 4.25+.

Blender is a free and open source tool you can use to model, texture, and animate 3D objects.

Blender supports several export formats, but the two most relevant to UE4 are FBX and glTF.

FBX Exporter

• Powerful and flexible, but hard to get right.
• You must answer questions about coordinate systems and units.
• Lot of options, but you can save a Preset for your export options.
• Blender FBX export code and UE4 FBX import code is difficult to understand and buggy.
• T68575 FBX Known issues & TODO's.

See Blender FBX Pipeline for more details.

glTF Exporter

Blender Ue4

• Standard defines coordinate system and unit scale
• Exporter handles converting to that standardized coordinate system, simplifies importer and user options.
• Models, textures, materials.
• Format can handle static models and animated characters, but UE4 side is still working on the animation part. For now, use FBX for now for animated characters.
• Does not support collision or sockets. [1][2]
