No offense taken. I suspect you don't have much experience with Vue renders. I suppose I had the same response when I first heard Terragen renders can take over a week. Even so, I found out later, it really depends on the TG scene and settings. Some TG renders are done in minutes, just as is the case with Vue.

Depending on scene and settings, if you use radiosity, you can set it up to not have to calculate radiosity for each render, thus saving considerable time. Also, spectral 2 clouds take longer to render than spectral clouds which take longer to render than 'regular' clouds. Different levels of anti-aliasing as well as other settings can affect render times significantly.

Even so, if you use the five render licenses which come with Vue, and a typical frame renders in an hour, it will render in 12 minutes on your renderfarm. Not too bad.
