My floor is flying in render

Hello guys.

I’ve got a problème. On my working windows my floor is on right position but when i render this floor is “floating”.

Look image, as you can see the floor is not at same position as working windows.

I dont know why.

Some advice ?

thank you

If you’re using displacement, make sure the base color is black or set water level to neutral value.

This is my material.

As far as i can tell from your material screenshot, your displacement map is mostly white, likely with only board gaps being black. In such case you have to set displacement’s max level to 0 ant min level to some small negative value. That would be in Corona material or in Corona displacement modifier applied to your floor.

Ok thank you. I will try.
