ExportSkyToTexture(Camera)

Export the provided camera's sky to a flattened cubemap.

Declaration

GetMainLight()

Main directional Light for the HD Render Pipeline.

RayCountValues	rayValues	Specifes which ray count value should be returned.

Returns

Type	Description
UInt32	The approximated ray count for a frame

HDRDataDetectedProperly()

Returns whether the data for HDR is detected properly from the device. If this returns false it is suggested that a calibration screen is used to set the min/max nits limits and paperwhite values.

ReleasePersistentShadowAtlases()

Release all persistent shadow atlas. In HDRP, shadow persistent atlases are allocated per light type (area, punctual or directional) when needed but never deallocated.
