How to correctly render the motion velocity buffer with SRP?

Hi~
I want to render the object motion velocity buffer in my SRP Pipeline.After reading the HD-Pipeline,I try to implement it with a similar approach

Code (CSharp):

1. RenderObjectsVelocity()

set the camera depthTextureMode to

Code (CSharp):

1. DepthTextureMode.MotionVectors | DepthTextureMode.Depth

set the RendererConfiguration to

Code (CSharp):

1. RendererConfiguration.PerObjectMotionVectors

and render my "MotionVectors" shader pass,i got the buffer rendered successful.But after check the render loop of my pipeline,i found that all of my scene object with the shader which contains the "MotionVectors" is renderering even it is static,i debug the HD-Pipleline,only the moving object is renderer in the stage,what did i missing to get the non-moving object culled ? THX..

 

Need Help~~ ops..
