Title: Humming-Top
Post by: racoonart on 2012-09-05, 12:04:36

Hi there,
I discovered Corona yesterday and had some hours to test it. First i need to say: It's awesome! I'm really amazed by it's speed and already pretty usable features. Lightning fast! Keep up your excellent work!
This image here is based on an old Vray scene which was ridiculously easy to convert to Corona Materials. I'm having a lot of fun converting old scenes ;)

Hi,

an amazing result.

You can mail me on rawalanche@gmail.com if you want to test more recent build which might be faster and have some new features ;)

nice, what was the render time?

@ Mail sent :-)
@ Keymaster: It was about 45 minutes on a 3 years old dual-quadcore-xeon machine. I've been having breakfast while the image rendered so I can't say when it reached an acceptable noise level ;)

In bitmap settings, set bitmap blur to lowest value (0,01) ;)
Also "production defaults" is your friend :)

Anyway, great test. We are waiting on others!

Nice test,

I'm finding blur bitmap settings don't need to be 0.01 like mental ray.
Corona seems to handle the bitmap sampling better, I normally stick 0.5 to 0.2 works well.


cheers

In Vray I normally stick to summed area and a blurring of about 0.25 which seems to be a good compromise between sharpness and harsh edges in animation. But yes, Corona seems to do a good job without even touching the blurring ;) .

I think it currently depends on situation (sometimes you get way too much blur, sometimes you get just the right amount), there will definitely be more work in this area to make the behavior more consistent and predictable. Unfortunately the 3dsmax texmap API is very confusing and not documented.

in VRay i`m always turning off texture filtering. try that! :)
textures becomes very sharp and clean
