Floor rendering trouble

[GDE]

Hi,
I've got some trouble with the rendering level 3 and 4.


whereas with level 1 and 2 it's perfect


I'm working on an iMac-Mavericks and i've been trying with both the built app (Version Java 1.6.0_65 / 64 bit / 1 GB max) and the Java Web start version (Version Java 1.8.0_31 / 64 bit / 0,6 GB max).

Here is the model

Thanks

Your level 0 has a ceiling at 29 cms..... that is what you see.
Ceilings are shown when using the virtual visitor in Q3 and Q4, but not in Q1 and Q2.
