Why'd you choose  HD cache for sec.GI? I can understand you'd want to use it for interiorshots, but I think PT+PT for these exterior shots would be more effective.

I'd like to see a comparison of your scene when using PT+PT for both GI-quality as rendertimes.

Nice ground vegetation and trees by the way.Too bad some detail got lost on the trees when you replaced the sky background though.

Thanks RolandB, happy its of assistance.

Fellazb - I didn't really give much thought to the secondary GI at the time...I have been working with this setting for a while now and have been happy with its performance for both interiors and exteriors, but if I get some free I might run a test to see if there is a noticeable difference in time or GI quality. As for losing some detail in post, well I guess it's just one of those things. I often find areas of detail in RAW images that I really like that get a little diluted during the post stage. Its a trade off. Thanks for the feedback :)

Great images and nice details.

Fellazb : I also use PT+HD on exteriors, and I found that I got the same result in half that time. Especially regarding noise.

This is probably obvious but, if PT samples are increased for 16 - 32, then the pass time doubles.
If 16 PT samples takes 15min per pass on a 2k image, then 32PT samples would be 30min etc.

( btw this is on my AMD, will test once I get my workstation ).

Thanks Dervish. It's nice to be part of the PT + HD exteriors club :) This is one of the things I like about corona, there seems to be more than one path you can take and still get great results.

Kinda odd if you compare this to what others say about rendering exteriors vs interior.

I think the main difference between those to scenes is the complexity of light distribution. Especially when dealing with lots of detail, dark corners and artificial lighting when rendering interior shots compared to exterior where you mainly use only one lightsource (the sun). In that case PT+PT would have it's benefits because you don't lock up sec GI and get a constantly refinement of light distribution and therefor quality

The nice thing of Corona I guess is that a lot of combinations already yield in very good images straight away and considered to be o.k.
