Non-reflective floor being rendered with reflectivity

[pedrolramires]

Hello,

I'm currently trying to render some interior scenes but my concrete floors are always being rendered with glass-like reflection, regardless of the material and floor settings I use.

I'll be linking an example in this post.

There are no overlaping floors, it's 12cm thick and, for the purpose of testing, the settings used for this render were cranked down to the lowest floor reflectivity possible (material has 0% reflectivity and floor family has .95 radiance absorption) but it's still reflecting the same way it was when I discovered this was happening.

Which Out of the box Revit material concrete did you use? Normally if I run into these issue, I would create my own using generic and apply concrete texture. This way I get better control than the default material.
