Reflective ground with white backdrop help

[x9nder]

How do I achieve this look in Octane with the specular reflection of the glasses on the ground and with a white backdrop?

Reference to achieve

I have only managed this so far with a specular material for the floor and a HDRI with some other area lights.

What I have managed to create so far

Would appreciate the help!

Have you tried making it a mirror and putting either a light or a lit white surface behind it?

Oh I found the solution thanks! Adding a light or a white background behind and adding a gradient to the opacity of the floor to remove the visible line of the floor creates that infinite look
