Shader Globals¶
The following contains an overview of shader global variables provided by default in ChilloutVR, enabling dynamic shaders that respond to player states, hardware info, and system features.
Runtime and Client State¶
These globals expose the current system time, instance data, user hardware status (e.g., FBT or controller battery), and client UI state.
| Global | Type | Description |
|---|---|---|
| CVRTime | vec4 | x: System Time Seconds y: UTC Seconds z: DayOfYear w: IsLeapYear (0 or 1) |
| CVRGlobalParams1 | vec4 | x: Ping y: Players in instance z: Left Controller Battery w: Right Controller Battery |
| CVRGlobalParams2 | vec4 | x: FullbodyActive (0 or 1) y: Left Foot Battery z: Right Foot Battery w: Hip Battery |
| CVRIsUsingVr | float | Whether the client is in VR mode (0 or 1) |
| CVRPlayerUpVector | vec3 | Up vector of the local player |
| CVRQuickMenuOpen | float | Whether the Quick Menu is open (0 or 1) |
| CVRMainMenuOpen | float | Whether the Main Menu is open (0 or 1) |
Camera Rendering¶
Provides information about the currently rendering camera.
| Global | Type | Description |
|---|---|---|
| CVRRenderingCam | float | 0: Normal Camera 1: Portable Camera 2: CVRMirror Camera |
Player Positions¶
These globals expose bone and positional tracking data for players in the instance. The local player is always at index 0. The order of remote players is not guaranteed and cannot be relied upon for identification.
| Global | Type | Description |
|---|---|---|
| _CVR_PlayerRootPositions | vec4[] | x, y, z: Root Position w: Avatar Height (meters) |
| _CVR_PlayerHipPositions | vec4[] | Hip Position |
| _CVR_PlayerHeadPositions | vec4[] | Head Position |
| _CVR_PlayerChestPositions | vec4[] | Chest Position |
| _CVR_PlayerLeftHandPositions | vec4[] | Left Hand Position w: Left Hand Gesture Value |
| _CVR_PlayerRightHandPositions | vec4[] | Right Hand Position w: Right Hand Gesture Value |
| _CVR_PlayerLeftFootPositions | vec4[] | Left Foot Position |
| _CVR_PlayerRightFootPositions | vec4[] | Right Foot Position |
Tip
These arrays are capped at 255 entries. Use CVRGlobalParams1.y to retrieve the number of players in the instance.
Custom Global Parameters¶
Provided by the CVRGlobalShaderUpdater CCK World Component that allows you to define custom global parameters outside of Scripting.
| Global | Type | Description |
|---|---|---|
| CVR_CCK_Global_1 | vec4 | Custom value from CVRGlobalShaderUpdater |
| CVR_CCK_Global_2 | vec4 | Custom value from CVRGlobalShaderUpdater |
| CVR_CCK_Global_3 | vec4 | Custom value from CVRGlobalShaderUpdater |
| CVR_CCK_Global_4 | vec4 | Custom value from CVRGlobalShaderUpdater |
Tip
Custom global textures can also be defined via CVRGlobalShaderUpdater. These textures are then accessible via the CVRTexturePropertyParser CCK Component.
