Well, like anything else there are trade-offs. I just downloaded TG as well. (I have Vue 4 DEsprit as my other terrain generator.) TG looks to have a baddly designed interface and I expect to be struggling with its learning curve. Vue, conversely, is intuative to get started with right out of the box without opening the manual. But I agree, Vue is difficult to achieve photorealistic results, at least with version the 4 that I have. But if they ever want to compete with Bryce and Vue and sell Terragen, then they had better put a better inteface on it.
