If I'm reading this right, I think that your building is about 20 units high. My
model is about 120 units high in comparison. If that's right, you should divide
the "7.5" in the df3_pattern line by 6 to get the blurring to about the right
level. It would also make sense to similarly adjust the "scale" statements in
the bozo noise functions as well.

Cheers,
Edouard.
