DOTS Instancing shader functions reference

Alongside the access macros, Unity provides shader functions that load the values of constants directly from the draw command data. Shaders that Unity provides use these functions.

Unity provides the following shader functions:

Shader function	Description
LoadDOTSInstancedData_RenderingLayer	Returns the renderingLayerMask for the draw command.
LoadDOTSInstancedData_MotionVectorsParams	Returns the motion vector generation mode for the draw command. This is formatted as a float4, which is what Unity shaders expect.
LoadDOTSInstancedData_WorldTransformParams	Returns whether to draw the instance with a flipped triangle winding. See FlipWinding.
LoadDOTSInstancedData_LightData	Returns whether the scene's main Directional Light is active for the instance. The main light can be deactivated for multiple reasons, for example if the light already included in light maps.
LoadDOTSInstancedData_LODFade	Returns the 8 bit crossfade value you set if the LODCrossFade flag is set. If the flag is not set, the return value is undefined.
