GTA 6 physics: bodies, water and destruction

GTA 6’s physics can already be seen in how people move, objects react, and water and fire behave. In official footage, jet skis leave trails across the water. After Lucia throws an incendiary bottle, flames appear on and beside the car. Rockstar has also explained how animations adapt to characters with different builds. Whether players can freely demolish buildings remains unconfirmed.

The strongest evidence comes from the official An Extended Look video and comments by Rob Nelson, head of development and co-head of Rockstar North, in interviews with Famitsu and IGN. Leaked footage provides other intriguing observations. Its origin matters: a clip from an unidentified build shows a particular moment that may change before release.

Where physics ends and animation begins

Imagine someone being hit beside a table. The scene must combine the blow, both people’s arm positions, a loss of balance and a collision with the tabletop. Some movement may have been prepared by animators, some adapted to the situation, and some calculated by a physics system. All three approaches can operate in one scene.

Dividing everything into “real physics” and “canned animation” is therefore too crude. A prepared punch can end in a physics-driven fall. A hand adjusting to an object does not mean the game calculates every muscle. Players see the result of these systems working together.

Graphics present a similar trap. The sun may move beautifully in a water reflection, but that tells us nothing about how a wave lifts a boat. To examine physics, watch the action and the environment’s response: what was struck, what moved, and how the motion changed. One impressive frame is usually insufficient.

Different character heights affect movement

Nelson told IGN about a specific improvement: the team can retarget animations to characters of different proportions during play. That includes NPCs. He illustrated the problem with characters roughly 168 and 188 centimeters tall. Using exactly the same animation, their movements would fail to line up in a fight or while interacting with a car.

The game now adapts the movement to the model, allowing Rockstar to create a wider range of heights and body types. This matters both in ordinary crowds and at close quarters: a hand needs to reach the right place, and getting into a car needs to account for someone’s size.

Animation retargeting and the physics of falling solve different problems, however. In official footage, Lucia hits a man in a store; his torso turns and his arms react. In an office shootout, opponents lose balance and fall among the furniture. These scenes show reactions to contact, but do not reveal every rule used to choose a body’s movement.

The same distinction applies to blood and injuries. Hit effects, health loss and physical movement may belong to separate systems. A blood trail does not establish that blood is fully simulated as a liquid, and one fall cannot promise every kind of injury seen in Red Dead Redemption 2. The moves themselves are covered in our melee combat and stealth article.

What we know about breaking glass

The claim about procedural glass has its own source. In March 2026, TwistedVoxel published a saved search snippet from programmer Brady Jessup’s profile. It mentioned work on a procedural vehicle glass-breaking system. This is an incomplete search extract. It indicates an area of development, but neither explains the finished system nor replaces a Rockstar demonstration.

“Procedural” suggests that rules generate the result rather than a single preset outcome. The snippet does not say which parameters GTA 6 uses. It gives no details about shard counts, whether cracks depend on the weapon, how long they remain or what happens when glass is damaged again.

Nelson gave Famitsu a more concrete example for players: breaking a car window during a theft sets off the alarm. The damage has a specific consequence. The sources examined here do not describe a complete system for shooting through cover or list which materials stop a bullet. See our separate weapons guide for the choice of weapons.

Cars: collisions, damage and repairs

In a leaked clip published by iPhones, a car hits a truck on a bridge. Fragments scatter and the car bounces beside the larger vehicle. It is a striking individual example, but cannot establish the rules for every crash: how another car responds, which parts can detach or how much damage changes handling.

Vehicle condition already has a confirmed gameplay consequence. Nelson told Famitsu that damage lowers the price of a stolen car. If the car is being taken for sale, collisions reduce the eventual payout. Pay n Spray can repair it.

There are two distinct questions here: what a collision looks and feels like, and how the game accounts for its outcome. The developer described the link between damage and price. His explanation does not establish the precise model for crumpled bodywork, damage to individual components or repair costs. Those need separate tests with different cars under comparable conditions.

Can buildings be destroyed in GTA 6?

There is no confirmation that players can freely demolish buildings. The official scenes examined show local shootout effects, flying fragments, fire and damageable objects. They do not establish that a house can collapse, any wall can be breached or a neighborhood can be permanently changed.

Popular percentages predate the current footage. In January 2025, iXBT relayed claims attributed to an informant named PainKiller: supposedly 40% of large buildings have accessible interiors and 60% of smaller structures can be almost completely destroyed. These numbers are rumors. The materials examined contain neither a verifiable full original post nor official confirmation of destruction at that scale.

Entering a building and destroying it also require different evidence. A store could have an accessible sales floor and breakable display window while its walls remain fixed. A moving door does not imply a simulated roof collapse. The percentage of open interiors therefore cannot measure destruction.

To understand the scale, we would need a sustained demonstration across several kinds of buildings: what remains after damage, and whether the same result is there on returning. There is no such basis for a general conclusion yet. We cover the city itself in our Vice City guide.

Water: a jet ski’s wake, a paddle and a dockside jump

An Extended Look shows three distinct actions. Jason jumps from a wooden dock and makes a splash as he enters the water. Jet skis then cross the surface, leaving pale trails. In another scene, Lucia paddles a kayak through calm urban water.

These scenes reveal more than a static sea view because water responds to characters and vehicles moving through it. They do not cover every condition. We cannot test how a heavy boat handles large waves, what happens when several vessels collide or how much a current changes their route.

Players have also discussed the jump. Some expected more visible deformation of the surface around Jason’s body. The footage shows a splash, rather than a large wave radiating outward. It cannot tell us which elements are physically calculated and which are added as visual effects.

Many broader promises about water trace back to an October 2023 Rockstar Mag article. It reported on new technology and work by RAGE Technology Group, but warned that some details described development goals and might never appear in the finished game. The article’s embedded 2016 water video was an example of the desired result, not GTA 6 footage. The writers presented surfing as a possible consequence, not a confirmed activity.

Visible waves, future water activities and the technical simulation of the ocean must therefore be assessed separately. Claims about rain and hurricanes also need their own evidence.

Hair, cloth and a shared bedcover

In a leaked clip published by iPhones, a dancing woman’s long hair moves with her head and body. It lifts away from her back and settles against it again, while individual visible locks change shape. This is a specific example of secondary motion lending the body a sense of weight.

It cannot establish that every hair is simulated separately. The system’s settings and the exact build used in the recording are unknown. Former Rockstar animator Mike York also singled out hair movement among the details that impressed him in An Extended Look during a TechRadar interview. His expert opinion is useful, but it does not replace a technical explanation from the GTA 6 team.

There is more direct testimony about fabric. A Famitsu journalist described Jason lifting a bedcover and getting into bed beside the sleeping Lucia. Nelson confirmed that the detail took considerable work.

This requires coordinated movement of the body, hands and cover. The account does not mean players can grab or tear any fabric in the world. Each object may have its own designed interactions. We discuss the couple’s domestic life in our article on Jason and Lucia’s relationship.

Plants, beach umbrellas, sand and fire

Two other short clips published by iPhones show small objects reacting to contact. Foliage bends as a pickup passes, and a beach umbrella changes position and folds when a character collides with it. Such details make driving through greenery or walking among loungers register in the surrounding world.

Scale matters here. Foliage moving does not show that a car can uproot any tree. A folding umbrella shows the behavior of one object, not a general rule for every street fixture.

The iPhones writer also describes sand sticking to bicycle tires and gradually coming off as the bicycle crosses a wet stretch of beach, with wheels sinking partly into dry sand. This is the writer’s observation of the recording. It suggests interaction between wheel and surface, but does not confirm that players can reshape the beach or dig permanent furrows.

Fire can be examined in official footage. After a chase, Lucia gets out of a car and throws an incendiary bottle at it. Flames rise along the car and separate burning patches appear on the ground beside it. The clip does not show fire spreading through a building, how long it burns or how it can be extinguished.

Why you cannot drop even a cup anywhere

Nelson explained a revealing limit with an everyday example. In the protagonists’ safe house, a cup has to be taken to a place where it can be set down. Players cannot drop it on the floor or leave it at any arbitrary spot. He was discussing Jason and Lucia’s shared living space.

This shows how Rockstar chooses the extent of interaction. An object can look convincing in a character’s hand and feature in a complex movement, yet have only a small set of permitted actions. Detailed physics alone does not turn every object into a freely usable player tool.

How long consequences persist is another question. The materials examined do not say how long shards, bullet marks or moved objects remain after the protagonist leaves. We therefore cannot yet describe experiments with collision chains and revisiting a damaged location as established features.

Is the physics better than GTA IV, GTA V and RDR 2?

Footage and interviews highlight specific elements: animations adapting to different bodies, everyday interactions with fabric and objects, hair movement and reactions from small objects. Vehicle damage has a described practical consequence, a lower sale price. Together, these facts still do not amount to an overall rating of the physics. Fabric behavior, vehicle collisions and human balance must be compared separately.

A broad comparison needs matching conditions: similar blows, obstacles, speeds, surfaces and repeated attempts. Scenes cut together for a video may differ in staging, camera position and purpose. Particular care is needed when comparing an early GTA 6 leak with the finished version of another game.

For now, assessing each demonstrated element on its own is more useful. Rockstar has explained one important animation system, and footage shows several clear physical interactions. The overall limits of destruction, persistence of its effects and behavior of the world under arbitrary experiments remain to be tested.
