A Look at NPC Locomotion Tech Developed for Half-Life Alyx

Here's a behind-the-scenes look provided by Joe van den Heuvel, one of the Alyx team members.

Half-Life: Alyx has turned one a couple of weeks ago and what a better way to celebrate the date than with a look at locomotion tech developed for the game. The footage was originally shared by Joe van den Heuvel, a developer at Valve. 

The developer wrote that the system "used procedural stride retargeting so the characters would stay exactly on the path without foot sliding, backed by a motion matching solution to pick the closest available clip."

He also shared some details on how they approached metrics and made the final system produce organic results.
