Render ZDepth render element pass normally


Hello, I want to render a ZDepth render element pass. The look of the particles are larger than rendered normally. I understand that this will work better but for my purposses this will not work. I want to use the ZDepth pass as an obstruction layer in After Effects. The problem is that the blocking of forms are chunky. Is there a possibility to render the ZDepth render element with the same result as you render normally? I hope you understand my question.
