Thanks, I will try using the models, when the manual arrives.
Also tried using the custom modifiers but it's applied to all floors so I can't add a ceiling (for buildings with 2+ floors for example). Is there a way to use custom modifiers for specific floors only or will this be added in a future update, if it isn't available now?
Yes, this feature will be added later. In fact it is already in there you just need to manually edit the .dat file by adding "floor 1" etc to each block but it will be overriden by next editing of custom tiles. I will add the option in the editor in the future as it's not tested with 9 floors (it was made when there were only 4 floors available).
