Fstorm render

[joconnell]

Just a thought. Maybe, big ticket productions get a lot of things free. I could imagine that software and hardware are giving in exchange for a mention. You know, the rich pay far less for things than the poor. This could be why they used FStorm.

Hmm, a lot of the big studios I know make decisions about software because they don't get anything for free. They might get preferential support because they're buying 100 licenses of something or 1000 render nodes but the cost of the software is a huge factor. One place I know looked at vray versus a gpu based solution to take into account interactive lookdev stuff but then their average shot production cost including render license cost and render node cost, production features of the renderer and how quickly they can get a frame out with the standards that they need. There's loads of different factors!

Could you please add a quick test with Vray RT as well?

Here is a test between Vray RT and Redshift. Couple of things to know first, one Redshift only uses 93% gpu on main display card (Sometimes drops lower) so you can use your computer still, Vray was at 100%. Also the quality of the Redshift render looks better to me, although weirdly enough the vray render is cleaner in the dark areas even compared to itself in the light areas. Hard to set each exactly the same for rendering. I love Vray RT but it really doesn't compare to Redshift, Vray RT lacks a lot of features and doesn't render a lot of things correctly like normal maps and bump maps, and I find it a little clumsy at times, taking long to load a render or crapping out. Vray RT really needs to catch up. Don't get me wrong Redshift has some things to work on also, but at the rate of it's development it won't be long.

After uploading the renders I noticed the Forum downgrades and scales down the images, so it's hard to see how much cleaner the Redshift render is in the lighter areas.

Very cool test, thanks for sharing.
Bump maps look different in the different render engines. We have the problem that we have two engines under one name and when comparing them there are differences. I agree we have to improve on that and we are actually working on it.
The grass often seems greener in the other garden, but I think that for the same time RT is cleaner and better (like with more GI bounces) in general. But I am also (very) biased .
Being involved in the dev process I can assure you that we are working hard to make things better. Having your feedback helps a lot to keep on right the right path. Feel free to send such here or directly to blagovest.taskov@chaosgroup.com

Thanks,
Best,

Thanks Blago, it's good to hear you guys are working on RT. Seemed for a while like development was put on hold or something. I just used Redshift for a complete rendering test on a project, next we will be using it on an animation. Would be nice to have Vray RT as an option, but right now in production for us that is proving not so.

Also just as a note, Please check bump mapping again, I'm not talking about looking different, I'm talking about just not looking or acting right at all. I started a few threads about it in the past.

We have a lot of users using RT GPU for production, both stills and animations and they are very happy with the results, finding RT GPU the best solution or their case. But of course users should use whatever suits them best for the particular task.
Otherwise, the team got even bigger, we are doing the opposite of on hold .

Best,
Blago.

But on the other hand, it's easy to see how much noisier it is in the darker areas

Despite the very obvious GI bounce AND secondaries intensities clamping.
Is this RS 2.0?

Good to hear Blago, we just couldn't get it to do what we needed for animation with large amounts of geometry

Yeah like I said it's weird, vray is cleaner in darker areas, but also it's cleaner in darker areas than it is in lighter areas itself. But redshift is quite a lot cleaner in lighter areas

I don't know about that, I had the bounces set the same I'm pretty sure. Not in front of the computer right now. I also put it up for no clamping. But it is 2.0

Don't get me wrong I loved RT but in the past two projects it couldn't handle the jobs so we switched. I'm not one of these people that switch and go back and trash there previous render, I'm just giving my experience with both. On a side note we are still using vray adv for some projects.

Yeah, no worries - I really appreciate the feedback. We know that we have more work to do

Big images: rmc -> open in new tab, or download and look at 1:1



Not all is as hype would have it.

[Donfarese]

Hmm... That seems i unbelievably long for RS render.Mind sharing scene.

Just got home an looked at those images, the RS ones don't seem like the GI was set up right knowing how it acts with correct settings. Due to the incredible noise in certain areas.

[^Lele^]

i can surely share the render settings.

Thanks Lele. What software do you use to analyze the Noise?

[Donfarese]

Did a new test that you guys can download if you want and try yourselves. Just for the record, there is no speed problem with VrayRT, it's really fast and I actually like the way it's set up better with just the "Max Noise" setting. I'm hoping Redshift adapts a more "Max Noise" approach. Redshift is much more complicated to set up, think of old vray. But it's complication is good in certain situations for large or complicated animations. The thing that Redshift does so well is it's super stable, and has tons of features and support for max shaders...etc. I couldn't find one area of working with it that I had to say, oh damn I can't do that.

Below is the tests, You'll see that Redshift actually took 3 seconds longer, but is much cleaner even though it's hard to see in the compressed versions on the forum.

Vray BF + LC 4min 9sec

Redshift BF + IPC 4min 12sec

Redshift IC +IPC 54sec

Since it is really hard to tell on the forum (Makes the Redshift render look a lot more noisy than it is) I included a zip with the actual renders, called "Render Scenes.zip"

[vlado]

Can you also post the hardware used for these renders? Just to make sure we are not comparing a single i7 against 3 Titans, for example, as happens so often on various forums...
