Help! Floor will not render!

Hi,
recently I purchased a Dojo environment:
https://www.daz3d.com/kendo-dojo-and-outfit-for-genesis-3-female-s
But when I load this scene and try to render it, the floor will not render. I looked up all parameters, everything seems to be ok. But I can do what I want, change height or move it slightly - it will not appear in the final render, there is a big "hole" instead. All other props are rendered properly.
Anybody an idea what is wrong?
Greetings
Rael

Make sure the floor isn't below the Environment Ground.
It's definately above the ground. I also lifted it up, but it will not render still....
how thick is the floor. In some prgrams it has to be thikcker than 1 px I think it is.
hm now its to see on the jpg... strange...
I take it you are using the right presets for the render engine, Iray or 3Delight?
