A5 vs A6 test

[rozumny]

We did a little test, to compare the rendering speed.

Interior scene with only Corona Sky from the windows. No other lights.
First we rendered the scene on Alpha v5 once, then we installed Alpha v6, and rendered it twice.

The settings were:
PT, HD 24 samples
MSI 0.0
HD cache
Precomp density 5.0
Record quality 512

Alpha v5 has done 120 passes in 1hr 32min 10sec
First attempt with Alpha v6 was 109 passed in 1hr 32min 38sec
Second attempt with Alpha v6 (after restarting the computer) was 120 passes in 1hr 31min 04sec

So actually there was no much difference in speed between A5 and A6. And the amount of noise looks quite the same.
With different scene the results would be different too probably.

But we love the Corona Renderer anyway!
Its a wonderful product!
And A6 has a lot of nice enhancements!
The IES lights for example - render much cleaner than before!

Make sure shadows are not disabled anywhere, for curtains for example.

And make sure glass materials refraction mode translated properly to A6. Especially make sure that caustics is disabled for window glass.

We will check on that. Thanks!
We did not change any materials or settings, just opened the same scene and pressed Render!)

There may not be any performance problem, but i would just like to make sure :) You have quite good CPU and resolution is not so big, so i think the scene could render a bit faster. To be clean in about an hour, instead of noisy even after hour and half :)

I checked the materials on caustics, the curtains on shadow casting - everything seem right.
I would love it to be without a noise in 1 hr, but maybe I dont know all the corona tricks yet!))
