Hello,

I was interested on this CGTalk thread,

--- LINK ---

This guy, with Titan X + GTX980Ti, in 18 minutes, and with his new FStorm GPU renderer for 3ds max, can obtain this image.
I'm always fascinated by new rendering engines =)



So, I converted (by hand) the scene  for Corona ( I have the permission from DronK)

Next, my test, with a good, old I7 970 @ 3900Mhz. Not bad for a 4 year old CPU ^_^
With a new 5960X (in overclock), we can reduce more than half the rendering time ;-)

Corona 1.3 (commercial version)

CPU = I7 970 @ 3900 Mhz
Res =  1024x1024
Pass = 130 pass
Rendering time = 30 minutes

Feel free to render this scene and write here your result.

--- DOWNLOAD ---

Unfortunately, the red shader is too glossy and it doesn't match exactly the original version.
Also, the lamp intensity is too low. Sorry.

15 minutes



30 minutes



60 minutes

Can you try embeding the picture correctly ? I can't see them here or at cgtalk either without direct-clicking.

Anyway, very interesting renderer, saw it earlier on cgpress today. Tonemapping and Glare look very nice ! Good to see these are priority from beginning.

Now the images show up.

I would love to try optimizing this scene for Corona. I am just afraid that soon there will be some misunderstandings and hasty conclusions...

We really need glow/glare features in corona. Look how much nicer the main light, highlights and exterior is in the FStorm render.
Vray who?

You can do it in post. But yes, do it inside 3ds max, like in V-Ray, it can be very interesting =)
Maybe in the new Corona VFB ;-)

Doing glares in post basically nullifies any frame-buffer tonemapping (or post-production at all), since you need linear output.

Yes it's flexible, but it pushes further the distinction that rendering "requires" 'blackroom' type of finishing  to make complete render (not complete image).

I prefer post-production to add artistic/creative touches, not all the technical things that make render look correct and real. Renderer should work like modern-day DSLR, it should output good looking product, which may, or may not require a touch-up.

VFB+ does nice bloom, but not glare : /

Wow..this renderer looks really good and interesting. Has a lot of potential. Love the glare and glow. Just wow! Love apps that pay attention to little things like this as it reduces time and gives u a better idea of final imagery without post. U can even see the subtle glow and glare in the reflections of the other models.

Can i try optimising this scene?

Also it looks that there is one light sorce behignd first camera is missing in corona version.

About bloom and glare i think it is better when it stays out in postprocesing.

why don't just use corona test scene to show engine capabilities instead

Because I wanted to compared the original FStorm scene to Corona.
Obviously, Corona wins. If someone with good CPU ( 5960X or Dual Xeon) can try this scene, I think in 10 minutes can obtain a clean render (with my old CPU = 30 minutes)
I don't know how to optimize this scene. I think I did 90% correctly..
This scene has very easy lighting and shader setup.

I tested some stuff, but I am not going to post anything as:
-it is hard to compare CPU and GPU - what should we consider? Price?
-it is hard to reproduce materials - they will probably never be the same
-I could not set some things the way they are set in FStorm - for example environment - I managed to align it more or less the same way as in the original scene, but reflections are different - in FS you have this nice blueish reflection in the floor and table, I didn't manage to get similar result in Corona

Can you put it in dropbox or anything more convenient because in free mode the dl speed is really slow

Yes Maru, of course... I know...
(*) My conversion is simple conversion. But it look 90% similar.
(*) Blue reflection is caused by the texture in the FS enviromnet. In Corona, I had only a CoronaSky. But, this doesn't change the final result and the quality/noise.
(*) My test is just a RAW test.  This scene can be called a "test-simple-interior-production-scene". It's for fun =)

But,  it's nice to see how a 4 years old CPU (200 euro?) can do a similar result with a Titan X + GTX980Ti.

VFB+ does nice bloom, but not glare : /

I haven't tried the VFB+ , but i'm guessing it applies the bloom after the render is finished or canceled/stopped. Like most other 3dsmax plugins. A nicer way would be applying it while rendering, even if with a temp lower quality or resolution. Like Octane does with the glare and bloom.
 Is the Octane the only one with this approach ?  Not sure how Arion / Maxwell are doing it.

You can use it interactively, just by default it is set off (only after finish), to create more fluidity.

Hi,
For fun, test with Corona. Core I7 5960X - GTX 980 et Titan X.
13 et 14 mn.
For now, invest time and money in a GPU solution is far too expensive. Until two days ago, I worked with Lightwave and Octane. To work properly with Octane, ie without noise, you need ten to twelve video cards Titan X or GTX 980i.
My friend Richard - Ensign3D - work with twelve cards. Investment from 12,000 to 14,000 € !!!! and put 20 minutes to make an interior scene when I put in 40 to render the same scene with Max and Corona - € 290 / month.
I prefer Corona !
Now, Corona with Lightwave, I am not against.

Sorry, but with ten to twelve video cards Titan X you can obtain a clean render in 1-2 minutes ;-)  (V-Ray,. Octane, Arion, etc...)
There is something wrong in his setup.
Corona is fast, but not so fast, compared with 12 Titan or 980 GTX ^___^

Wut? I belive i can render this scene in 2-3 mins with 6-9 xeons pluged in wich will be still cheaper than 12x titans.

I will show tests later today. (Xeons are bussy)

Meanwhile single CPU test. Latest daly build with new fancy denoiser.

For high-res (5k +) ? Noisy-free interiors.

I do believe Octane is faster than Corona, but these supposed times are bit funny. Even with Corona, people claim 1 hour renders :- ) But my renders take 20+ hours for example.

I ment for benchmark resolution. Full resolution 3200x3200 (as on Fstorms website) should take around 6-8 times more ... ughm time. Somwhere around 1-1.3h not more.

Juraj, I'm talking about my FStorm benchmark =)

(*) Corona + 1024x1024 +  old I7970 = 20-30 minutes.
(*) FStorm (Octane, V-Ray etc... ) 1024x1024 + 12 Tytan = 1-2 miuntes ^__^

Denoise is another story.... It's post-process!

1 hours, with Corona, with simple interior and FullHD res is possible, I think.

I think he meant random production scene, not this benchmark :- )

12 Titans isn't such bad setup, I like the idea of stacking GPUs together rather than building full CPU-based nodes.

The modularity of such platform is big plus.

I once considered building something like that once high-vram GPUs would come, but now I am very content with cloud (Rebus).

Here, without denoiser 130 pases. Sample error 11%. With 5 nodes Twin X5660 Xeons.

3200p - 28min 22 sec

1024p - 3min 26 sec

With 5 nodes Twin X5660 Xeons = Intelligent configuration =)

RAW cost:

Twin X5660 =  1.300 euro x 5 =  6500 euro

(*) 980 GTX = 500 euro * 10 = 5000
(*) 3 PC nodes = 500 euro * 3 =1500
(*) TOT =  6500 euro

With 10x 980GTX you can do a lot of things, very fast for interior... but:

(*) 4 GB VRAM (forget complex outdoor projects)
(*) 10 GPU + 3 nodes eat  A LOT, A LOT of electricity! More than 5 double Xeons, believe me!

Honestly, I prefer Xeon Config.

Don't these new GPU renderers have Out-Of-Core rendering features? If that is the case then the vram problem is not that much of a problem anymore, or is it?

Does Octane ? I know only for sure that Redshift does, which is technically pretty revolutionary renderer. With that said, Out-of-Core almost always come with performance hit. It's not exactly like harddrive swapping, but neither a magic bullet solution.

The 16/32GB next-gen cards, which are around corner, are the true solution.

Yes, it does. But you can only use it for textures, not geometry.
And yes, it comes with a little performance loss.
