This tutorial shows another way to use the sector within a sector idea to create both the insides and outsides of buildings.


Firstly, you have a large sector that will be an exterior scene and you want a building in it.


Cleave out a sector within the large sector. In this example the inside sector is 4 JK units by 4 JK units by 2 JK units high. In some cases I have given the sizes of things I have cleaved out, but use whatever you think looks good.


Rename the sector to a new layer (Building) so you are only dealing with the inside sector. Then spilt the sector horizontily 0.6 JK units from the ground. Name the lower sector "Buildingrooms" and the upper sector "Buildingroof". Display only Buildingrooms and align the grid to the floor so that you are looking straight down on the grid. Cleave the sector 0.2 units all the way around. This becomes the Eaves under the roof. Cleave the inner sector 0.1 units all the way around. The 0.1 sectors become the walls.


Cleave across the 0.1 unit sectors to make allowance for windows and doors. Note that where an interior wall will meet one of the exterior walls, you need to allow 0.3 units, to mimic the way a real house is built.


Cleave in some interior walls and allow for doors in them. You should be able to see that this example is a building with a central hall and three rooms off each side of the hall.


Delete all the 0.1 sectors that are not windows or doors. The blue bits on the picture below are the sectors that were deleted in this example.


An elevated view shows what we have achieved so far.


Texturing the floor shows the partial bits of wall we have constructed so far.


Switch to a side on view and using the 3D preview, select each doorway or window sector in turn and cleave them. In this example, doorways finish 0.4 units from the ground so cleave the top off and delete the sector. For the windows cleave at 0.1 units from the ground and at 0.4 units from the ground and delete the upper and lower sectors. The picture below shows the result from a single window and doorway.


The next picture shows the partially textured building with all the doorways and windows done.


Next, we will do the roof. Switch to the buildingroof sector.


From a side view, cleave this sector up to a peak.


From the next side around, do the same on the central sector. This results in a roof coming to a single point from all four sides. Obviously, heaps of variations are possible. You can delete the central sector now and have a solid roof. However, we are going to apply the same technique we used on the walls so the result is a hollow roof.


Cleave from each side again, 0.3 unit below the first roof cleaves you did. Delete the new sectors you formed and leave the central sector and you now have a hollow roof from the inside.


Finally, here is the finished building partially textured. Sorry about the colours I chose.


A few points to note...


Good luck and I hope you can make use of this technique.
