Hey John, Everything is great now!
I just want to trouble you with one more question please.
I would like my towers to not be so tall, rather somewhere around 100-200 meters. When I change the crater depth/diameter the tower shrinks, but some strange stuff happens too. For example, the render may cut off part of the image, or the render will not look like the preview. This does not seem to happen in your file though. Other than that, should I be changing all of my related settings, strata, distribution shader and so on to match the new depth?
