Wanted to see how far I could get with Corona in under an hour. :)
Rendering was 20 passes in about 12 mins.
Some post in Nuke.
-
i liked that warm post :3
-
that's some nice tonemapping, very subtle very nice
-
Thanks guys, I've got a small animation as well.
Details and scene file can be found on my blog.

Cool !
-
Just a quick mood study of a simple scene. Happy New Year! :)
-
The brick's look awesome, are they geometry or displacement?
-
Brick was done using displacement from a MightyTiles map. Was happy to see it worked with Corona. :)
-
Cheers man, I might look into mightytiles...any tips for getting such a clean displaced result in Corona? I often have the nasty black seam problem or edge overlaps (I know you can apply a smooth modifier, but I don't like the way the way that affects the objects shading).
-
wow !!
how did you setup that displacment.
I have also test mighty tile but the displacment look weird even if i make a smooth of 180° on my wall
-
All I did was select all the polygons (Edit Poly) and first clear all the smoothing groups.
Then, with everything still selected, just set everything to the same smoothing group (1 in my case).
For the displacement settings, set the size (view) to 0,5 pixels and slowly up the iterations while test rendering to get the desired sharpness.
For the MightyTiles side of things I ran it through a Color Correction node set to "Monochrome" to make sure I've got grayscale values.
Then I added a micro noise map to it using a mix map set to 10% mix to give it just a little roughness.

thanks for the tip.

Three grass shots done with Corona, promo material for my new Grass Generator (http://www.themantissa.net/blog/2014/1/20/grass-generator-v1) script.
Everything was scattered using Corona Scatter.
-
last one good.
-
Wooow what a nice script!! This will be usefull.

vey nice pics man!
is it really cool from you to share your script as a free tool...
lets try it!

This one had to cook about 15 hours on an i7 3770 for 2K, settings could probably optimized. :) (PT + HD)
Was getting about 1M rays / s.
Using a portal actually significantly slowed the scene down, so no portal was used.
-
you need 2 powerful Xeons.
17 hours for this scene?
you should save every 4 hours and see if something changes.

So this must have been a misuse. :)
-
I drew a single poly plane just outside of the window and gave it a coronaportal material, afaik that should be it? :)
It could've probably cooked a little less, but it took quite a while to get all the noise out.

Strange. Maybe there was solid glass in front of it?
-
Glass is set to hybrid... (Double glazing with thickness per glass)
Just had a look at the scene to make sure I didn't miss anything, without the portal I'm getting about 800k rays/s, with the portal about 650k max.
I flipped it both ways and tested to make sure I didn't mess up the normal direction, but slower regardless.
Keep in mind the scene is lit by bounced GI rays only. The sun hits the vegetation outside, which in turn lights the interior.
I just figured that's why it was a fairly slow scene and just let it cook overnight for 300 passes. I'd say it's almost noise-free around about 250, but still a fair difference with 300. :)
-
congrats ! I really like the mood in this picture...
-
So I think this would be the right place to bitch about the need of some v-ray\mental ray like object properties or even better some kind of a modifier with similar properties - something like cast\receive gi on\off displacement settings, caustics etc. all in one place would be really welcome. And yes simple portal option in v-ray's light is there for a reason so such scene as yours would greatly benefit from such or similar option in corona's one. Hope Ondra reads this :)
Nevertheless great render and mighty useful yet simple script you've made thanks for it, but I got one advise - even from mine not so big experience doing exterior\vegetation I can still say that in Corona you shouldn't use refraction on grass or any leaves - it always kills rendertimes without any noticeable benefits in terms of beauty/realism - try it with just translucency and some little reflection and maybe even not just white or grey but with a slight green tint. Here http://forum.corona-renderer.com/index.php/topic,2657.msg20865.html#msg20865 people give some nice tips about those materials - trees mostly but that setup works great with grass too - try it you will not be disappointed :)

More green stuff! :)
First one with A6, feels even faster!

An animation this time, building on an image I'd made previously.
