public MotionVectorGenerationMode motionVectorMode { readonly get; set; }

Unity configures the

unity_MotionVectorsParams

built-in shader uniform to calculate motion vectors in HLSL code.

For ray tracing instances,

unity_MotionVectorsParams

is a vector uniform. Its component values are as follows:

the x and z components are 0.
the y component is 0 if the motion vector mode is MotionVectorGenerationMode.ForceNoMotion. Otherwise it is 1.
the w component is 0 if the motion vector mode is MotionVectorGenerationMode.Camera. Otherwise it is 1.

To access the ray tracing instance matrix in closest hit, any hit, and intersection shaders, use the

ObjectToWorld

WorldToObject

HLSL functions.
