Well, the layout is definitely derivative.
I find that my method of modelling creates a few issues with Rayscaper render so I shall have to look into new mthods with each floor level a group and lights outside of these.
There are a number of artifacts which come and go to an extent. The tops of the walls and the floor texture have a dark weblike appearance which I suspect has to do with light levels.
Otherwise a case of moving on a little by little, test and redo.
