Rendering Problems with open spaces of different levels

[kuntzepeople]

Hello together,

I have open spaces of different levels. In edit mode you are able too look through the open spaces, but during the rendering the floor also apears on the ceiling.

The picture shows on the right the edit mode. We are on 1. floor and can look down to ground floor and also to the 2.floor what is only to keep the roof.

The left picture shows the rendering. You are not able to look to ground floor, and a ceiling appears on top of 1. floor.

Thanks in advance!

Check the visibility of the ceilings of the rooms at floor 1.
A ceiling is visible only from below in the 3D view, but is visible from both sides in the photo creation tool at the two best quality levels.
