The length of the control sector will determine the amount of sloping. And to align a sloped 3D floor to two
different floor heights, the length of the control sector must match the length of the actual floor.
No, as I said, that just makes it a lot easier to do. It is perfectly possible to make a control sector for a sloped floor of a different length to the play sector and have it turn out as you want. All you have to do is wrap your head around exactly how the slope will be with reference to the heights of the control and slope-to sector and the length of the play sector. It's nothing like as easy as doing it in the way you suggest, and I certainly don't normally do it myself, but there are times when it can be useful to do it (eg limited space) and I have done so. If you are familiar with splitting normal sectors and applying slopes to them, then the principle is basically the same.
So, to be clear, all I am saying is the method outlined already in this thread (and illustrated by my examples) is the way to go (ie aligned sectors of the same length for teh win

). It's easiest and in 99.999% of cases it would be foolish to do otherwise. However, it is incorrect to say that it
needs to be done that way.
