dx11.pointCloud Transparency an blur

Hello All,

I am working with dx11.pointcloud and would like to know if there is a way to make the constant (dx11.pointcloud buffer) transparent. There is no alpha input. Is there another way to control the opacity?

Also, I would like to make the pointcloud have motion blur which is a texture. I have made motion blur by rendering a texture and applying the affect to a quad, but then you can not see through the particles to objects in the background.

Thank you all for the help in advance.
Kind regards,

easiest way to turn off depth buffer for alpha layers

just use hsl color join and set the alpha value there.
dont forget to use the blend node so that alpha value changes get visible.
