vray and corona

[mitviz]

one big benefit so far to using corona until now for me was the denoiser which came out and render times and the way the lights looked inside interiors, you did very little and things just looked realistic out of the box, idk its hard to explain until you try it, before the last few months it wasn't really usable because you needed to waite forever for renders to clear up but since 1.4 version its really fast and at the end the denoising was just amazing, on some massive scenes i could stop a render at say 15 mins and have something very usable to look at. but now vray will soon have a denoiser then i guess competition is heating up which is good for everyone but there is no reason why anyone wouldn't have both, they are both fantastic and i bet one way or the other you will have to come across assets or scenes you will need to handle in both renderers and you will then need to know both but a vray user can easily learn corona, there is nothing to it only a corona user will have a little learning curve by trying to learn vray...plus in corona there are no splotches, man i hate them in vray, in vray you have to turn up settings to get rid of those babies in corona just render away so there are some benefits in my book, but personally i wont care so much once the denoiser is out, less render time and faster images

...does anyone have or know a script that would change Corona files into VRay?.

It's only because you, like so many older V-Ray users, stick to the irradiance map and stubbornly refuse to just use the default BF+LC settings

us cranky old farts. (seriously though i love Imap, but i must admit im using it *much* less these days. not on stills for about 6 months.. ... still the only choice for the caching and multiframe incremental though..)


having said that, when i do use imap, i cecrtainly dont complain about the blotchies though. i adjust to remove them, or switch to BF.. theres always a price to cutting corners eh?

Hah! We have this same thing happen in house. I've switched to BF (and LOVE IT) for easily the past 12 months if not more, and our other 3D guy still uses IRMap and still complains about splotches. Needless to say I have told him countless times to switch.

What I generally love about VRay is how you can totally bend/brutally f*** up/massacre the **** out of it in every way so you get a desired result. Want it physically correct? No Problem, out of the box. Want to fake ****? No problem you can nearly always adjust everything to your liking. Very flexible.

issue i have with BF and LC is time, it takes forever on my machine and IR map is so fast in comparison, as soon as denoise is there am down for BF but for now, not touching it with a ten foot pole

The reflection models are different; the V-Ray ones are Blinn, I'm not sure what they ended up in Corona, probably GGX.

Left images are V-Ray, right are Corona.

It´s a bug I reported here

It's not really a bug; that's how the "fix dark glossy edges" option works. I can't really change that easily. A work-around is to use a different BRDF.

I am sorry lots of you guys have broken version that is slow, produces splotches along with different kind of problems.

I guess i somehow got fully working version of vray. Who knew i am so lucky, i could have end up with broken version just like you guys.

[mitviz]

are you serious about the broken versions thing?

this maybe should be mentioned somewhere. No one would expect this option to change the glossiness the way it does. By default Blinn and fix dark glossy edges is set. This will especially on a floor always produce wrong results.

I guess he's not..

Define "wrong"? I've seen floors that reflect exactly like that. In any case, there's always GGX; it will probably end up being the default at some point.
