First of all I would like to say thank you for your hard work, and wish to see the growth of your Render Engine.

Please find my thought only as suggestions:

1. First and most important it
   is the scene conversion, let me explain why it is so important, your
   engine is pretty yang and the way you will find new users is only from
   existing ones. And here the best way to bring them from competitors is
   take the scene and maximum help user to get the "same" result
   after conversion. I can tell you that on my experience this is the most
   important stuff. Currently I am using couple of different engines and each
   of them work best in different situations. I would say the biggest success
   for Corona Render over Vray is all about how they people who first time
   tried their product is was able to almost continue working with their
   scene, and now it extremely easy to jump from vray to corona because you
   get almost 90% result of final image. I would suggest to spend a little
   more time on conversion part, this will make the transition much faster.
   
2. Second is simplicity, as you
   could see all engines not go to simplified interface, and put all
   difficult stuff under "expert mode check" or so. First of all
   your product is for work, not for tinkers, and as professionals render
   artist I would choose instrument which will save me time, that’s why
   Arnold render is on the peak for production, even for their slow speed,
   but you will choose the simplicity and consistent result in all different
   situation. That’s why render man is not so popular for small businesses.
   
3. I really like how your engine
   is handle the amount of geometry, but still think that global noise update
   is little old fashion, I really like how the latest builds of CPU render
   engines is using adaptive calculation, a surface with solid color cleans
   firs and details and corners last, you just get much faster understanding
   of final result.
   
4. I would move or duplicate
   Post parameters to frame buffer, this will help control the image faster,
   and now this getting more common.
   
5. After conversion lights which
   were instances, became all unique.
   

This is just short list after 20-30min of using. I will continue play around with this and will try to give you more my thoughts.

And again thank you for giving this pretty cool engine to the public, I think it has very huge potential.


Best,

Eduard
