Control Rig for Unreal Engine 5 by Lincoln Margison


Release date:2024, March

Duration:07 h 15 m

Author:Lincoln Margison

Skill level:Beginner


Exercise files:Yes

This course is tailored for game developers, starting with detailed explanations and instructions to guide you through creating procedural animation systems using Control Rig. You’ll gradually explore various features of Control Rig while creating a procedural walk system and experimenting with character interaction and realistic movement within the environment.

Next, we’ll delve into creating a procedural turn-in-place animation system, covering troubleshooting, tweaking, and step-by-step logic development. The project file includes completed versions of all creations for Unreal Engine 5.2 and 5.3, with updates planned for version 5.4 upon release.

The techniques covered are applicable to both single-player and multiplayer projects, as well as UEFN (Unreal Engine for Networking). While animBP access is currently unavailable in UEFN, preventing combination with keyframed animation, the majority of concepts explored within Control Rig remain applicable.

This course offers exclusive insights and knowledge derived from years of experimentation with Control Rig and procedural animation systems. My aim was to distill this experience into an easily comprehensible course, providing explanations and diagrams at every step to help you master Control Rig for your own procedural and dynamic animations.

I eagerly anticipate your participation in the course and encourage you to share your creations and ideas. I’m available for discussions on concepts, ideas, or assistance with any project, even if your specific use-case isn’t directly covered in this course.
