I agree T.Ed is not bad at all, my only minor problem with it is that it won't output a single 51x512 mesh like I want it too, but instead a series of 64x64's instead. But it's a good looking editor, intuative once you get into the mindset, the landscape painting tools work well as does light mapping. It's definatelly a good, well featured landscape editor with numerous output formats. I espically like the paint at height tool, which saves alot of time.
I lay upon my bed one bright clear night, and gazed upon the distant stars far above, then I thought... where the hell is my roof?
