As an architect, rendering images are important but should not be a major consumption of our daily life...at least mine anyways. Ive looked into other packages such as Vray for sketchup, podium, kerkythea. Some thing was missing and there was too much tinkering and learning curve. :dho: Ive invegstigated MAX, Maxwell, Cinema 4D and so on but these packages have a steepER learning curve with them and not no mention high associated costs. 
Packages like this are suited to full time renderers....But in saying that, Twilight render is intuitive and easy to use. I can render a scene well enough without consuming too much time AND have the quality of those OTHER packages.
(based on the little time Ive had on it, Ive tested it on some if my models to see if it was worthy 
)It didnt take me long to notice it in the Sketchucation forum...(yes...ill admit, ad banners are PITA but I hit the banner) It took me only 4 days to jump on buying a licence. After going through the video and pdfs, it was easy to use (Kudos to the pdfs...as i refer back to them) All I can say is TEMPLATE...that came pretty close to world peace for me
That made my workflow....that much easier.Kudos to Fletch and Chris (I think) for developing this great product.
I also see there is quite a following from all over the world....and producing/ed great renders.
Cheers
