I am not sure if this is intended or just some confusion on my part. I've set up a simple scene with Unity 2019.4 and Post Processing v2.3.0 with a Camera, a Directional Light and a Cube with Default-Material. The Camera has a Post-process Layer component and a Post-process Volume component with only the Motion Blur effect. When the Cube mesh renderer component has the option Motion Vectors = Force No Motion, the Frame Debug actually shows an extra SetPass call to the MotionVector.Render -> MotionVector.RenderJob -> Draw Mesh Cube. When setting either Motion Vectors = Camera Motion Only or Motion Vectors = Per Object Motion, and the object does not move, the extra SetPass on the MotionVector.Render disappears. Is this a bug or just bad naming? How can one disable Motion Vectors for specific meshes entirely?
