Hey,
Is there any option to control buildings height? Maybe by using some polygon options?
This I would like to know also. One of the updates changed the tower at my home field to some 40 story international airport type tower. It is actually about 4 stories tall.
You can always dra a polygon around that house, remove it, and add another default house that match the real house better. To bad there is no list with like thumnails to make it easier to find what you search for in the default FS objects, so it can take some time to find an appropriate object.
