Shadow and reflection amount on VOP

[stezza]

So here you can see a VOP has been applied to the ground to catch the shadows and reflections, but the result is very different on the render pass you just cant see the orange glow from the lamp....why is this?
Thanks for any help

You can see here the orange glow disappears during rendering when object prop turned on.
I need to capture that orange reflection..

Not sure. Could you simplify the scene and attach it?

Here is a test scene with the cosmos lamp.
You can see the orange rgb in the vfb but not captured with vop is on.

Thanks. The light's reflection seems to be rendered fine, but it is very dim. Change the Background color to something similar to the non-matte picture and you'll see it better.
