Reversed Vray versus Corona rant

[Neilg]

You can DIY a lightmix in fusion without too much trouble. by using embedded exr's and calling each light element 'group1' and 'group2' etc, it's re-usable across everything you create.
You should never render final images like that anyway as it's too slow to generate the channels, but it's useful for scenes with complicated light setups and really nailing out what the final light values and colors should be with no trial and error.

[Nicinus]

That's really how I see the use anyway. I saw this nifty video where they were playing with the lightmix while doing a test render, and once they were happy there is a button that allows you to copy all the values to the scene lights for final render. I would really like to have this functionality.

corona is really only for those 'Scandinavian apartment' people or maybe a car or leaf render to use as instagram likes.
every tried doing a massive masterplan or super heavy 1500 frame in cornrona? its going to be a pain

Sorry but is true, he is pure unbiased.

can't help but chuckle everytime I hear this.

Actually I have to disagree with this. Our studio just wrapped up a birdseye rendering of a 40 acre piece of property with 3 structures on it and forest pack items for grasses, meadows, trees, etc and Corona did just fine. Not saying VRay in bucket mode wouldn’t have been more memory efficient, but I think the whole time the scene never went over 32gb for the final high res image and IPR worked quite quickly. We rely pretty heavily on Lightmix to ‘art direct’ the lighting, otherwise we probably would have been using VRay on that one.

Well, on a high res car interior with the full bells and whistles like DOF and night lighting, Corona performed quite poorly. Especially since the introduction of adaptive domelight. This speeds up rendering car interior rendering considerably.

Yeah, I thought that was Maxwell's b.s. talking point

Maxwell had a lot of potential back then, and it kind of started the whole trend of renderers with which you don't have to fiddle too much. which, in retrospect, seems to show that their idea had at least some merit. but yes, all that talking about unbiased rendering created a lot of confusion.

[vjaramillo]

Yes...lightmix and a new VFB would be awesome. That's the only reason why Corona looked attractive. Being able to adjust lighting in realtime would be awesome vs. having to render out tones of light selects and comp them in post. Re: light portals. A thing of the past. At least for me.

[Nicinus]

There was a preview shown almost three years ago, so either the project was shelved or it is one of those where they are rethinking it over and over. Last and worst alternative is that the particular programmers involved just can't seem to get it our of their hands. VFB2 and Lightmix seems to be the top on most wish list so it would be wonderful to get a real timetable.

Looks like you missed the newer preview. It's a bit more than a year old. https://forums.chaosgroup.com/forum/...3-vfb2-preview

When you’re talking ‘how many years’ since the last update on a feature, it’s been a while...

If I were to read between the lines a bit, it seems like Chaos Group perhaps over extended themselves with a variety of VRay ports and new ventures and are currently understaffed but rallying (!) and noticing user input (Lightmix? Roadmap? Vfb2?).

It seems to happen a lot with firms as they grow. Certainly seen it with architecture firms. It’s not a bad thing. A firm gets to a point where they don’t want to say ‘no’ to new opportunities and growth but it really stretches their existing business model so they hopefully adapt. Just my off-topic two cents when it comes to all these threads about support, software competition, vfb2, etc.

I’ve got 4 2080 Ti’s in my cart and my finger is hovering over the ‘buy’ button so I’m mostly just hoping Vray really takes it home over the next few months with RTX, lightmix, etc.

*shrug*

2 x 2080Ti will be fast and work with NVLink in Vray GPU - definitely worth a try!

Great, thanks for the feedback! Maybe I’ll just pull the trigger on two of the Asus Turbo’s. I can always get 2 more later...

The price of Corona vs V-Ray is all you have to look at, you pay a premium price for a more robust and feature rich render engine with V-Ray, Corona is for those that don't need all the bells and whistles, still team ChaosGroup. I love V-Ray!

V-Ray just needs much, much more exposure and marketing and specifically social media marketing so people can see with their own eyes how great and complete a rendering solution V-Ray has always been and just how much easier and faster to configure it has become.

Try finding current V-Ray videos or comparisons or render tests of V-Ray on YouTube for example and there are very few, where as years ago there were tons, so newer CG artists have nothing to see that would let them know how incredible V-Ray is currently.

As an example I've recently purchased a Redshift license due to it being app agnostic, this render engine is rapidly growing in popularity it is good but it is not better nor faster than V-Ray... I did a ton of comparison renders for my own curiosity and satisfaction because I hate hype and like to actually know what's what, and I can say definitively for my own knowledge that V-Ray Next GPU is considerably faster while delivering a cleaner image.

It is also so simple to optimize it's crazy, I mean all you really need to adjust is the Noise limit combined with the V-Ray denoiser and you can dial it in exactly where you need to be quality vs frame time.

I mean come on now, only one setting, how much easier does rendering optimization get than that, it's phenomenal!

And V-Ray CPU is not much more difficult to optimize than that running BF+LC... basically just Noise limit, Bucket mode min max samples + the denoiser, V-Ray is a dream that gets better and better year after year.

Redshift is great but the optimization takes way longer in that all the samples are tweak-able separately which looks good on paper but ultimately takes way longer bumping samples, comparing render smaples tweak some more all for slower grainier results vs V-Ray Next GPU results.

Can I also just mention how amazing the V-Ray denoiser is and what incredibly clean and consistent results it returns, Redshift has Optix but Optix is not really for final frame beauty renders so it's results are usually muddy and destroy detail.

If this one feature of V-Ray could get more marketing attention it would blow people away, I did some demos for an architectural firm that was thinking of switching to Lumion lol , because they did not want to upgrade their old V-Ray licenses.

Basically none of those folks had even been aware that IPR rendering was even a thing, and that along with the denoiser had peoples eyes popping out of their heads, needless to say they upgraded all their V-Ray licenses.

This was about a year ago now but it made me realize that people are just not aware of the current amazing state of V-Ray, I hope the news can be shouted way louder because V-Ray deserves the crown now more than ever.
