Workaround for reflection on pure white floor

[Lubo]

Hello,

can someone tell me, how to get a reflection on a pure white floor? I`ve render my scene as an exr File with separate reflection pass, and it works very well, but not on a white floor. I think that it`s not "realistic" but my customer want it

Best regards

Lubo

It should just work with a white glossy material.
What kind of setup do you have?

Thank you for your reply.
Sorry, I didn`t have explain it very well.
My setup is similar to yours. But as you can see in the new screenshot it don`t works in the post. If you want to change the "strange" of the reflection with the opac value you see the darker plane of the diffuse layer.
When you masked out the cube the reflection disappears on the pure white enviroment layer.

So what I really nead is a reflection layer with alpha channel as you can see in this vid https://vimeo.com/119848103 on 08:52
I try to rebuild his setup but I can`t. I think the vid is too old.
