Try this comp. "Receives Lighting" unchecked in the Phong works fine for me.

basically You can have as many override3D / 3D replace materials / 3D renderers as You want, so You can dissect the scene into Your Own "render passes"

Idea is that I have a live footage. It is tracked in SynthEyes. I need shadow only casted on the road. So, I am making a road in Fusion via a plane. I only need shadow of another object on the road plane,and not the whole plane. I need any part of the road plane that is outside the shadow to be transparent.

just merge it and set the mrg as "multiply" - white areas will be transparent

Add a ChannelBooleans after the render node & connect both inputs to it
Set the Operation to Subtract
To Red > Red BG
To Green > Green BG
To Blue > Blue BG
To Alpha > Red BG
