I have abandoned my heightmaps, which were laughable in comparison to LumpyPats maps here...
Since then I have added very few things, just testing and what not. LAst night I modded for the first time in a couple months. I do this from time to time. Get bored with it, then its all I think about for a week or two, and its all i do for those weeks.
I also saw today that MERP project has their own new site which looks great and the work they are doing looks even better.
Last night I played around with some regions and LODs.
