Title: Corona 1.4 major new features
Post by: Ondra on 2016-05-05, 17:22:34

Hi, just a quick announcement: These are the major new features in Corona 1.4, and also the features we need you to test most in the release candidates (see https://corona-renderer.com/blog/corona-1-4-release-candidate-and-betatesting-giveaway/ (https://corona-renderer.com/blog/corona-1-4-release-candidate-and-betatesting-giveaway/))

• Corona now efficiently samples more than 255 lights in the scene
• Added VFB history and comparison
• Max 2017 support
• Added virtual reality camera - as option in Corona camera modifier
• Added texture baking
• Added adaptive image sampling
• Added denoising
• Added velocity render element
• Added interactive and multiple render region drawing into Corona VFB
• Corona Scatter: Generating instances is now multithreaded. Speedup for typical quad core i7 is about 5 times
• Corona Standalone is now part of the installer. If installed, it will be used automatically with the "Export+Render" button - no need to export to a folder where the standalone is copied. Still somewhat experimental
• Switched rendering of all Corona Light/proxy/scatter display modes to nitrous. Drawing a lot of Corona objects (proxies/scatter in wire/pointcloud mode or CoronaLight) in a scene should now be faster.

Many thanks Ondra,
I'm sorry, but where "adaptive image sampling" ?
Thanks in advance
Franck

Hi Franck!

It is enabled by default. If you do want to find the settings for it, it can be found by checking the "Enable devel/debug mode" in the Performance tab, and it's listed under "Adaptivity and denoising" toward the bottom of the options that are exposed.

Hope this helps!

Adaptivity balances the calculations across the image, to focus more processing on tricky areas, normally places like shadows, to reduce those times that you find yourself with a clean image in the "easy" areas but still needing more render passes as you wait for one problem area to clean up. The option is tucked away as normally no reason to turn that off - but you can give it a go for testing (the new A/B comparison in the VFB history, plus render regions, is a great way to quickly compare differences in different settings).

What a great update!

I'm using RC3. It can reduce render time by (at least) 60% with denoising+adaptive.
and thanks to "noise level" that can tell when you should stop rendering, you don't have to ask yourself "is this good enough?" anymore.
Also, multiple render region is really great, and render region+ IR are super fucking great combo.
