I've been using D5 for about a year now. It's a great renderng tool, most likely the best one currently out there. It has a good asset library (I wish there were more free items).
A reliable chat, messaging and a streaming platform. Great for 1440p streaming. Used it regulary for 3 months. There are some issues but it's a good tool. Sad tosee they're closing it so soon.
A great and easy-to-use rendering software. I love the lighting system and the fact that it's not power-hungry like other rendering tools. My suggestions would be to improve the material editor and the UI.
