Did you look at rendering>batch render...? ;]

Nice results. Is it A5 or daily builds, you are using for these renders? I'm asking this, because whenever i try to render displacement wirh procedurals on A5, max always craches.

This was my first attempt at corona rendering. I was very amazed how fast i was able to learn basics of corona. Especially after mental ray :]

And how one could answer your question without knowing how your material setup looks?

And what do you know - it worked like a charm! :] http://forum.corona-renderer.com/index.php/topic,2466.0.html
Thanks for the help, everyone.

I saw the other guy on forum posted beautiful renders with vcm: http://forum.corona-renderer.com/index.php/topic,2450.0.html and wanted to try it myself, but run into problem of excessive fireflies. Fortunately with the help of other coronauts, here in forum, i managed to find a solution. It seems that vcm don't like bluriness in reflection and refraction slots. Especially in refraction. Put some map in that slot, other than white and you'll get a horde of fireflies.
Anyway here's my attempt:

Fixture on ceiling in my scene has material with light emission on it, but it's very weak. Light source that simulates flashlight near camera, is corona light. It's small (20mmx5mm) and extremely powerful - 20K units of intensity. I tried to change its shape to sphere, but fireflies grew up in orders of magnitude :]
My system units is in mm.
I decided to make very simple scene to experiment more with caustics and after many tries and errors, i found one way to completely get rid of these nasty bugs. I found that setting glossiness value to 1, in reflection and refraction, gives fireflies free image. Now i'm trying to fix all materials in my main scene. Will see if it works in more complex scene.

Keymaster and Dolphinoff, thanks for answers. Unfortunately, changing random sampler didn't helped a bit.
I tried to hide all objects with glass and metal materials on them and all fireflies has gone. Then i unhide big flat mirror - no fireflies, but as soon as i started to unhide small curvy objects with high specularity materials, those nasty creatures started to crawl back :[ My typical chrome material has 0 diffuse, 0.5-0.6 reflectivity, 0.96-0.98 glossiness, 18-25 IOR and glass - 0 diffuse, 0.8 reflectivity, 1.54 IOR and solid shadows. Not sure if i could change these settings much without altering believability too much.
Somehow i think that biggest secret of fireflies free picture from Dolphinoff, is lack objects with complex shape and high glossiness in his scene.

Sometimes i get impression, that people gets spoiled easily by the speed of corona. Soon they'll start to complain about corona not rendering in realtime :] As myself, i came from mental ray here, so it never ceases to amaze me how fast this renderer is.

Yes, unfortunally, light is small and very strong. I even used a little directionality on that light. I'm not sure if it can cause any problems. Glass is solid on all objects, as far as i recall.
Btw, does changing such parameters as PTS, MSI or LSM, have any influence on image quality in VCM mode? I did some test region renders while changing those and didn't notice any significant changes.

Wonderful results. Could you show your render settings? I tried to do something similar, but all i get is ton of fireflies, even after 5K passes.
