11 Overview

33 Grand Theft Auto VI is expected to use a procedural animation system based on technology described in multiple patents filed by Take-Two Interactive, the parent company of Rockstar Games. The most prominent of these is a Rockstar patent filing, titled "System and Method for Virtual Character Locomotion," which describes a data-driven framework for generating character movement in real time rather than relying solely on pre-recorded motion capture animations.

55 Note: Patents describe technology that a company has developed and protected, but they do not guarantee that the patented features will appear in the final shipped product. The following information is based on patent filings and is subject to change.

77 The Virtual Character Locomotion Patent

99 The primary patent (US11620781B1) was filed by Take-Two Interactive on October 23, 2020. The listed inventors include Tobias Kleanthous, Mike Jones, Chris Swinhoe, Arran Cartie, James Stuart Miller, and Sven Louis Julia van Soom. Kleanthous, who served as a lead AI and gameplay programmer at Rockstar Games from 2014 until late 2021, is identified as the primary inventor and author of the patent.

1111 How it Works

1212

1313 The system breaks character movement down into small, reusable motion segments that function like building blocks. Instead of creating a separate full animation for every possible scenario (walking, walking in rain, walking while injured, walking uphill on gravel, and so on), the system maintains a library of motion fragments that can be dynamically stitched together based on the character's current state and environment.

18-One of the most significant implications of the procedural animation system is its potential effect on NPC behavior. In previous GTA games, NPC animations were drawn from a fixed library of pre-recorded motions. This meant that NPCs in the same situation would move identically, and the variety of NPC behavior was limited by the number of animations the studio could produce and store.

18+One of the most significant implications of the procedural animation system is its potential effect on NPC behavior. A fixed library of pre-recorded motions makes NPCs in the same situation move identically and limits variety to the number of animations a studio can produce and store; recombining small motion segments avoids that limit. Previews of the August 2026 Extended Look reported that the game contains more than 600,000 NPC animations, although Rockstar has not tied that figure to the patented system.

2020 Related Patent: NPC Intelligence

2121

2222 A second Take-Two patent (US11684855B2) addresses NPC intelligence and pathfinding at scale. This patent describes a hierarchical pathfinding system combined with personality modeling and server-side processing. The combination of these technologies is said to enable a significant increase in the number of active, intelligent NPCs that can be rendered simultaneously while maintaining realistic behavior patterns.

2525 Performance Benefits

2626

2727 Traditional animation systems require a separate pre-recorded animation file for each distinct movement. As the number of scenarios increases, the storage and memory requirements grow proportionally. The procedural approach described in the patent achieves comparable or superior visual quality while reducing animation data requirements, because the same small set of motion segments can be recombined in countless ways.

2828

2929 This efficiency has two practical benefits. First, it allows the game to support a wider range of character animations without a proportional increase in storage space. Second, it reduces the computational cost per character, potentially allowing more animated characters to be active simultaneously. This is particularly relevant for GTA VI's dense urban environments in Vice City where crowds of pedestrians, drivers, and ambient NPCs need to move convincingly at the same time.
