PhysicsSettings

When set to true, physically simulated objects will stop being simulated if they have little to no motion for a set period of time.

When set to true, parts that are BasePart.Anchored will show a gray surface outline on the surface of the part's bounding box that is currently facing the ground.

When set to true, each physics assembly is assigned a unique color and the Part associated with the assembly are outlined with the color. Parts that are attached together by JointInstance will share the same color.

When set to true, shows the center of mass for each physics assembly. This property must be set in the Physics tab of Studio's settings menu.

When set to true, parts that are actively being physically simulated will have a red outline.

When set to true, Part will be outlined with a specific color, depending on the state of its root simulation body.

Body Types#

When set to true, displays collision cost annotations for parts. This property is not scriptable.

When set to true, draws force vectors for constraints on selected or hovered instances. This property must be set in the Physics tab of Studio's settings menu.

When set to true, draws torque vectors for constraints on selected or hovered instances. This property must be set in the Physics tab of Studio's settings menu.

When set to true, draws contact force vectors for selected or hovered assemblies. This property must be set in the Physics tab of Studio's settings menu.

When set to true, each contact island will render SelectionBox adorns on the parts in contact islands, where each contact island is assigned a random color.

When set to true, sphere adorns will be drawn at the contact points of each part where physics interactions are occurring. Each sphere also has an arrow drawn in 3D, facing the surface that the contact point is detecting.

Solver Variations#

The behavior of this property varies depending on whether Roblox's physics engine is using the PGS Physics Solver, or the Spring Physics Solver.

This is controlled by the Workspace.PGSPhysicsSolverEnabled property.

Spring Physics Solver#

When Workspace.PGSPhysicsSolverEnabled is set to false, the contact points are color coded as listed below. The length of the arrow extruding from the sphere depends on how much force the contact point is exerting, and what the contact type is.

PGS Physics Solver

When Workspace.PGSPhysicsSolverEnabled is set to true, the contact points are always colored RED, and the length of the arrow will always be 1 stud. There are no special conditions tracked, because the PGS solver does not keep specific lookup tables for the states listed in the Spring Solver.

When set to true, draws gravity force vectors for selected or hovered assemblies. This property must be set in the Physics tab of Studio's settings menu.

When set to true, XYZ axes are rendered at the BasePart.CFrame of every part.

When set to true, displays magnitude labels alongside drawn force and torque vectors. This property must be set in the Physics tab of Studio's settings menu.

When set to true, every individual mechanism of parts is given a unique color.

An ancient property that hasn't work correctly since late 2007. It's supposed to render an XYZ axis on the root part of a Model, but the axis rendering component doesn't work correctly.

When set to true, parts that are not BasePart.Anchored will be highlighted. This property must be set in the Physics tab of Studio's settings menu.

When set to true, each player's character is outlined with a unique color, and each part that the player has network ownership over is outlined with the same color.

An ancient property that hasn't worked correctly since late 2007. It's supposed to render a large XYZ axis in the center of each BasePart, but the axis rendering component doesn't work correctly.

When set to true, a cylinder is drawn around each player's character, representing their Player.SimulationRadius. Each physically simulated object will check to see which player is closest to that object, and if they are within the player's simulation radius. If both conditions are met, that player will becomes the network owner of that object.

When set to true, each solver island is highlighted with a unique color. This property must be set in the Physics tab of Studio's settings menu.

When set to true, shows terrain replication streaming regions. This property is not scriptable.

When set to true, shows physics timestep information for assemblies. This property is not scriptable.

When set to true, parts that aren't aligned on the 1x1x1 grid will be outlined yellow.

An ancient property that hasn't worked correctly since late 2007. It's supposed to render a large XYZ axis in the center of the world, but the axis rendering component doesn't work correctly.

When set to true, Roblox will fall back to using its legacy CSG solver when performing solid model operations.

When set to true, disables CSGv3 for plugin solid modeling operations. This property must be set in the Physics tab of Studio's settings menu.

When set to true, draws the net force from all constraints on selected or hovered assemblies. This property must be set in the Physics tab of Studio's settings menu.

When set to true, draws the net force from all contacts on selected or hovered assemblies. This property must be set in the Physics tab of Studio's settings menu.

When set to true, draws the total net force on selected or hovered assemblies. This property must be set in the Physics tab of Studio's settings menu.

When set to true, enables temporal smoothing for force and torque visualizations. This property must be set in the Physics tab of Studio's settings menu.

Sets the scale of arrows drawn for aerodynamic force visualization. The default value is 1.0; smaller values draw smaller arrows and vice versa. The default value is a good starting point for a wide range of aerodynamic mechanisms.

When set to true, forces the use of CSGv2 for solid modeling operations. This property must be set in the Physics tab of Studio's settings menu.

Sets the scale of arrows drawn for force visualization. This property is not scriptable.

Controls the number of frames used for force visualization smoothing. This property must be set in the Physics tab of Studio's settings menu.

When set to true, shows physics interpolation throttle information. This property is not scriptable.

This property is supposed to show the BasePart.ReceiveAge of a part, but it does not work correctly.

When set to true, the joint connections of each part, and the states of their underlying primitive components are visualized as a spanning tree.

Spanning Tree Table#

There are several visualizations made available when this property is set to true:

Controls the throttle rate of Roblox's physics engine. By default, the physics engine will adjust the physics environment throttle depending on how much work the physics engine is doing, and the current framerate. See the enum page for EnviromentalPhysicsThrottle for more information.

When set to true, the underlying collision geometry for PartOperation and MeshPart is rendered.

When set to true, enables aerodynamic visualization for selected or hovered mechanisms in Studio's play and run modes. This visualization shows aerodynamic force, torque, and center of pressure for the hovered or selected mechanisms.

When set to true, displays instance names alongside drawn force and torque vectors. This property must be set in the Physics tab of Studio's settings menu.

Controls which metric is used for solver convergence visualization. This property is not scriptable.

Controls the visualization mode for solver convergence. This property is not scriptable.

If the PhysicsSettings.PhysicsEnvironmentalThrottle is set to DefaultAuto, this specifies the maximum time that the physics environmental throttle has to wait before it is allowed to automatically change.

Sets the scale of arrows drawn for torque visualization. This property is not scriptable.

If set to true, version 2 of Roblox's CSG solver will be used instead of version 1.
