Class SkyRenderer
Base class for sky rendering.
Namespace: UnityEngine.Rendering.HighDefinition
Syntax
public abstract class SkyRenderer : objectFields
SupportDynamicSunLight
Determines if the sky should be rendered when the sun light changes.
Declaration
public bool SupportDynamicSunLightField Value
| Type | Description |
|---|---|
| Boolean |
Methods
Build()
Called on startup. Create resources used by the renderer (shaders, materials, etc).
Declaration
public abstract void Build()Cleanup()
Called on cleanup. Release resources used by the renderer.
Declaration
public abstract void Cleanup()GetSkyIntensity(SkySettings, DebugDisplaySettings)
Returns exposure setting for the provided SkySettings.
Declaration
protected static float GetSkyIntensity(SkySettings skySettings, DebugDisplaySettings debugSettings)Parameters
| Type | Name | Description |
|---|---|---|
| SkySettings | skySettings | SkySettings for which exposure is required. |
| DebugDisplaySettings | debugSettings | Current debug display settings |
Returns
| Type | Description |
|---|---|
| Single | Returns SkySetting exposure. |
PreRenderSky(BuiltinSkyParameters)
Preprocess for rendering the sky. Called before the DepthPrePass operations
Declaration
public virtual void PreRenderSky(BuiltinSkyParameters builtinParams)Parameters
| Type | Name | Description |
|---|---|---|
| BuiltinSkyParameters | builtinParams | Engine parameters that you can use to render the sky. |
PreRenderSky(BuiltinSkyParameters, Boolean, Boolean)
Preprocess for rendering the sky. Called before the DepthPrePass operations
Declaration
public virtual void PreRenderSky(BuiltinSkyParameters builtinParams, bool renderForCubemap, bool renderSunDisk)Parameters
| Type | Name | Description |
|---|---|---|
| BuiltinSkyParameters | builtinParams | Engine parameters that you can use to render the sky. |
| Boolean | renderForCubemap | Pass in true if you want to render the sky into a cubemap for lighting. This is useful when the sky renderer needs a different implementation in this case. |
| Boolean | renderSunDisk | If the sky renderer supports the rendering of a sun disk, it must not render it if this is set to false. |
RenderSky(BuiltinSkyParameters, Boolean, Boolean)
Implements actual rendering of the sky. HDRP calls this when rendering the sky into a cubemap (for lighting) and also during main frame rendering.
Declaration
public abstract void RenderSky(BuiltinSkyParameters builtinParams, bool renderForCubemap, bool renderSunDisk)Parameters
| Type | Name | Description |
|---|---|---|
| BuiltinSkyParameters | builtinParams | Engine parameters that you can use to render the sky. |
| Boolean | renderForCubemap | Pass in true if you want to render the sky into a cubemap for lighting. This is useful when the sky renderer needs a different implementation in this case. |
| Boolean | renderSunDisk | If the sky renderer supports the rendering of a sun disk, it must not render it if this is set to false. |
RequiresPreRenderSky(BuiltinSkyParameters)
Whether the PreRenderSky step is required.
Declaration
public virtual bool RequiresPreRenderSky(BuiltinSkyParameters builtinParams)Parameters
| Type | Name | Description |
|---|---|---|
| BuiltinSkyParameters | builtinParams | Engine parameters that you can use to render the sky. |
Returns
| Type | Description |
|---|---|
| Boolean | True if the PreRenderSky step is required. |
SetGlobalSkyData(CommandBuffer, BuiltinSkyParameters)
Setup global parameters for the sky renderer.
Declaration
public virtual void SetGlobalSkyData(CommandBuffer cmd, BuiltinSkyParameters builtinParams)Parameters
| Type | Name | Description |
|---|---|---|
| CommandBuffer | cmd | Command buffer provided to setup shader constants. |
| BuiltinSkyParameters | builtinParams | Sky system builtin parameters. |
Update(BuiltinSkyParameters)
HDRP calls this function once every frame. Implement it if your SkyRenderer needs to iterate independently of the user defined update frequency (see SkySettings UpdateMode).
Declaration
protected virtual bool Update(BuiltinSkyParameters builtinParams)Parameters
| Type | Name | Description |
|---|---|---|
| BuiltinSkyParameters | builtinParams | Engine parameters that you can use to update the sky. |
Returns
| Type | Description |
|---|---|
| Boolean | True if the update determines that sky lighting needs to be re-rendered. False otherwise. |
