I have a light source in a hollow cylinder which throws a circle on a sheet
placed above it. The cylinder prevents light to fall directly on the Y plane.
The sheet is reflective, so I would expect reflected light on the plane around
the light source. But the plane remains dark. Any idea how to fix it? I'm trying
to emulate a white fabric with the sheet: partly reflective and partly
transparent.

It depends on whether you want diffuse reflection or mirror reflection.
In the former case you need this:

In the latter case you need this:

Thanks Warp, solved with photons.
