Hi efflux, sorry about my lack of reply. Issue: I am not getting the 'Notify me of replies' message when someone posts replies. I took this issue up with Oshyan some time ago and he said that it is a Microsoft problem that he is working on. However, it appears that it still is not fixed.
Glad to see you are still working of the variables of your setup. I, like Rich, am not privy of the deep math used here to ferret out paths to achieve more natural looking terrains; and, thank God for so many talented guys here like yourself who contribute ideas by way of files we can experiment with. Please keep on...
