Hi Guys,

Finally took the plunge and installed corona Alpha5 yesterday and after getting my head around a bit of the workflow, here is the result of my first image. I haven't let it go long at all (186 passes at 2000x2000 which took an hour and a half on my 2 x xeon) but I think the results are REALLY good considering I spent NO time on materials (and left a lot just as a test material) and lit the scene with an HDRI and 2 material portals.

For anyone interested, the settings were PT16 and HD Cache50 and I upped the secondary GI settings to PT512 with 300max records. Perhaps these changes were unnecessary but I tried to collect a few tips from suggestions within the image gallery from users that had submitted the works I liked.

I'm really interested to understand corona a lot better with the view to switching over from Mental Ray as soon as possible so please, C and C as well as pointers would be more than welcome.

P.S...I have attached a 2nd image with the stats bar up because I would like to better understand the lights section. It says I have 22,843 lights. I noticed that in the Aplha4 benchmark test there was only 1 light indicated. Have I done something terrible here that I need to be made aware of? :)

OK SO MORE THE NUMBER OF RAYS/S MEANS LESS THE GRAINY RENDER WILL BE?

I MEAN MORE RAYS/S = LESS GRAINY RENDER ?
using corona before it was cool :3

Each polygon from light-emitting object is counted as a separate light. Don't worry though, it will render reasonably fast most of the times even with high light count ;)
Rendering is magic.

I figured it was going to be a geometry/poly thing. Thanks for the clarification Keymaster. Appreciated :)

There is no rule for this but in most cases you should be able to have acceptable results after about 100 passes.
