Title: Tests and else
Post by: sadypisten on 2014-09-04, 22:14:23

My first attempt with Corona render. This is a rework of an old scene, with Vray.

I plan to do some other rework with Corona in the near future, and upload them here.

Here's a test with Dof. As I read on the forum, there are some problems with the out of focus highlights. With 200 passes (2nd image), Corona gives a smooth and nice Dof, but the highlights are remain very noisy. So I decided to make a render with 3000 passes. It took 7:38:01 to render, but the result is very smooth, and fine dof, with clear highlights.

This is because lots of AA samples are required to render strong DOF nice and smooth. When rendering an image with significant DOF, you should lower the "gi/aa multiplier" to 8 or even less, this will give you better DOF at the cost of GI noise. The best way to render such scenes would be using proper adaptivity (additional samples would be used only where required) but we have to wait for this. :)

btw, pretty image :)

Yes. I've read about that on the forum, and checked it, but with the same passes (the low 200) I got the same result, so I decided to make a new one with more passes. For a test, I think it's a good result.

And of course, thank you :)

But with lower GI/AA multiplier you would reach those 200 passes a lot quicker ;]

Exactly.

That's something I can't argue with. :)

On other old scene, with Corona. The original was rendered with VRay.

Not bad at all.
