RayTracingMultiGeometryInstanceConfig.motionVectorMode

Description

Motion vector mode.

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 or WorldToObject HLSL functions.
