Title: Keyshot 9
Post by: Rantech on July 08, 2019, 04:11:17 am
Hello there is already first information about Keyshot 9?

Title: Re: Keyshot 9
Post by: MQ on July 08, 2019, 05:51:48 am
There is some information regarding excellent GPU support (NVidia RTX cards, GeForce RTX 2080 being up to 7 times faster than a AMD 2990WX), a new denoising feature, an impressive cloth material generator and some other new stuff.

I'm shure we will get a newsletter with new information soon.

Last week was the KeyShot World 2019 in Germany and it was amazing.

Some features I remember from the presentation:
- Advanced Cloth material
- GPU Rendering (needs RTX cards)
- AI-Denoiser
- UV Wrapper in KeyShot
- Improved "rounded edges"

Just a note on GPU...
An RTX card is not required for GPU Mode. Any card from the Maxwell generation (e.g. GTX 980) or newer will work.
However, the rendering will be sped up significantly by having an RTX card, since our implementation can leverage the RT cores present on those cards.

Is the GPU acceleration limited to Nvidia cards? No sign of AMD/Metal for Mac users?

Hopefully the AI denoising isn't GPU bound.

I hope my memory is correct.
In the presentation they said that the denoiser is faster with a GPU, but it also works with a CPU (2.5 seconds?).

Ha, yeah, good luck with that! I know you are joking, but it really is a serious issue. NVIDIA is really breaking some new trails in terms of GPU's, and apple really needs to get over themselves. I mean, Steve's gone, time to do what is good for the customer, not hold petty grudges.  Jarred Land (RED Cinema) , one of the biggest advocates and lover of the Mac ecosystem literally begged apple at the last developers conference to open up NVIDIA support on the Mac. He offered to do it for them, and hand them the code for free.  Something Is odd at apple, and I just can't figure it out, but is a reason that I will probably not be updating my 2015 macbook pro with a new one.

Actually not :) Matt

I believe, that it's much harder for Luxion (and their small dev team) to cut their capacities for (let me guess) 5% more market share on Apple Pro users, than it would be for Apple to support NVIDIA and finally entry the pro users market. OpenCL and CUDA have different APIs - IMO a very hard task to implement and keep the maintenance running for both systems. For what?

You nailed it - somethin is odd at apple.  ;D

P.S.:
@Matt
I was sitting on my 2015 MB, waiting for some hot gear from Apple with NVIDIA support. Year for year, presentation for presentation my love to this company cooled massively down. Meanwhile I've bought two Windows systems (56x & 64x threads), each for a price where the new Mac Pro (8x threads) just starts. Now it's time for a new notebook - still no Pro solutions from Apple in their store. The Razor Blade 15 RTX 2080 with all the ports (no adapters  ;D) and power looks like something I could fall in love with ;)

Post by: mattjgerard on July 25, 2019, 12:44:02 pm
Man, I could have written that. Same story. Grew up on macs, loved the OS, really liked the integration with the hardware, but I fear that the pendulum has swung too far. When I was working 10-12 hours days video editing and compositing in AE working on my last version of the cheesegrater mac was glorious. It was still speedy, but now to get something at that level with current hardware I'm guessing with the new modular macpro will be unreasonably expensive. I did purchase and build a windows machine and bought a windows laptop in the meantime. I still use my 15" Mbp for personal use, but that will most likely be the last mac laptop that I buy. Which to me is just sad. With each iteration there is less and less stuff that you can do with them, and the price to performance ratio is getting stupid.

Anyway, png frame stack for alpha videos until Luxion includes the recently released apple ProRes codecs for windows. ProRes4444+ is a really nice looking codec.
Title: Re: Keyshot 9
Post by: Eugen Fetsch on July 26, 2019, 12:44:39 am
Hm, I don't see a necessity for a ProRes in KS. Working with single frames is much more reliable (at least for me). If something goes wrong, you can just render new single frames. I would rather like to see an implementation of Multilayer OpenEXR for having all the passes in one file. This format is Open Source and well documented.

There still are people that want to render full on videos directly from KS. I'm not one of them, and I know you and I are big proponents of NOT rendering video files (fistbump) but if one wanted to, ProRes would be the way to go. Its just a codec that would have to be implemented, so would be light work on Ks's side. I worked with ProRes since day one of Final Cut and apple, and its a great production codec.

I did a bunch of reading about EXR files a while back when I was getting into more compositing, and then I stopped doing ae work. Does After Effects handle mulitlayer exr files? I know houdini and I think Resolve can. Its a cool concept about having all the passes in one file and extracting them through nodes.

Post by: Eugen Fetsch on July 26, 2019, 07:54:33 am
It works fine with the Extractor Plug-In in AE. Natron, Nuke, Resolve, Fusion and Blender do it naively.

But now we are completely off topic :)

And (very roughly, won't hold you to it, promise) how much extra oomph would it deliver over my current CPU-only setup (Intel i7-6700 running at 3.4GHz)?

Soooo, anyone else running a beta copy of KS9, and your thoughts???

We currently don't have the "best" NVIDIA card yet (running a Quadro P5000 v419.17), but have one coming for a test rally drive.

Presently going through a whole routine test battery of renders to see how time vs quality suss out.

But honestly, imho the single most prickly issue I have had with KS is "real-time-rendering", even with a relative power house machine of 26 core, visualization of complex AND large assemblies (50m triangles) with multiple clear optical lenses (for the transportation lighting industry) has at best hindered my workflow and plagued my quality control. It has been virtually impossible to clearly see in "real-time" what the rendered results could bring.

 That said, GPU already appears to be offering unprecedented benefits toward this resolve. We are so very hopeful (even if rendering still needs to be done in the context of a "Network" paradigm). Thank you KS developers. It's a new dawn, it's a new day...
Title: Re: Keyshot 9
Post by: DetroitVinylRob on August 14, 2019, 11:25:38 am
Not sure what I'm going to get with GPU vs CPU rendering in that we noted one can no longer utilize the rendering option: Custom Control. GPU calls for either Max Samples or Max Time. The later, though I realize many folks like it in their particular workflow, does not appear useful to me. We have to have the highest res samples.

GPU in Real-Time-Render also doesn't appear to be faithfully displaying Global Illumination effects in reflections through multiple refracting lens materials. Hmmm.

Email [email protected], that's what I did. I only have a gtx980, so mine is BARELY supported, and in fact renders slower than the CPU. And I'll be getting a new workstation soon that will take my fps from 145 to over 400, so not sure I'll be dabbling with GPU rendering anytime soon.

Hi Eric. Do you have good reason to think an M4000 will handle KS9? That's what I have in my machine but I wasn't sure if it was too old (pre-RTX).

it should work, it just won't be able to take advantage of the newer gidgets and widgets of the newer cards. My gtx980 -which honestly is a 5 yer old card which is nearly dead with feeding tube by today's performance standards- will load scenes and render, but much slower than 24 threads of 5 year old dual 6 core xeons.

Post by: sotsupport on September 04, 2019, 09:59:48 am
Okay, between the blog discussing Keyshot9 and a comment here about compatible cards, I am a little confused about which cards will work with KS9 GPU rendering.  It sounds like any Nvidia card built on Maxwell or newer can run the GPU rendering, but only the cards with RTX cores can take advantage of the Real time raytracing and the AI denoising.  So my main question is, can those of us that have cards like a Quadro P1000 still see some benefit or improved performance using the GPU rendering option or should we stick with the CPU rendering? 

Also, is there any information on how GPU rendering is going to work with the network rendering product?

Thanks.

Only it is good that you dont need network render farm. You will buy 10 external GPU and put 2  GPU inside youe case and its done!

Ok i will see next news .... And keyshot will have upgrade on 8.3 ?

I would say YES. Luxion mentioned that KS GPU benefits mostly from the RTX technology.

RTX2060 has a performance increase of 30-60% (case dependent) in comparison to the 1060Ti, by default. The RTX core will be a multiplier to that value. How much, we'll see after the KS9 release ;)

Sneak peek, some of the numbers reported are for a P5000=106 seconds, same render on a RTX6000 = 35seconds

just beta non scientific results from the beta forum. And supposedly they are releasing a complete re-write of the GPU render soon so we will see what happens there.

Hey mattjgerard

many thanks for this Sneak Peak!

Could you (or anyone who has information on this) add a rough time of any-kind of CPU to this comparison?
Just to get a feeling for it how fast this is.

Would be a big difference for the importance of GPU-path in KS9 if e.g. a 16core TR would be 120sec (nearly as fast as P5000) or 300sec...

If no time is available, a really rough factor in comparison to a named CPU type would do the trick...

Our GPU render times so far (without Global Illumination) with Quadro RTX 8000, 6000, and 5000 show a huge performance jump (time wise) with 6000 vs 5000, but also a relatively huge roll off in improvement from 6000 vs 8000 respectively. Regardless of price currently, the 6000 seems to be the sweet spot performer in our tests. We also see "real-time rendering" that is visually consistent (clarity wise) with our GPU render time performance. This of course may all change as KS9 continues to develop.

Ref: We utilize PCs running Windows 10 PRO on HP Z6 Intel(R) Xeon(R) Gold 6128 [email protected] 3.40 GHz 3.39 GHz (2 processor) 64GB RAM (usable) 64-bit operating system, x64 processor and 12 core/24 thread.

Network Rendering 220 cores RenderA 28m33s RenderB 30m33s w/ global illumination

These where standardized render files and single camera positions of the same rather complex transportation lighting assemblies.

The performance is measuring time it takes from initiating a render, to completion.

Each result was an average of three attempts of the same task. Not wholly scientific, but reasonably accurate I believe.

I'm not sure at all. It is not available on my current beta version. Has anyone seen from KS a decisive word? Perhaps we will just have to wait and see... Possibly some highlight will be presented at What's New in KeyShot 9 Thursday, October 31st, 2019 11:00 AM PDT webinar.

So... my preliminary findings... i9 9900k, Quadro P4000, ground and global illumination, 100 samples:

Image 1. cpu, no denoise: 4:49
Image 2. gpu, no denoise: 1:28
Image 3. gpu, denoise set to .5: 1:42
Image 4. cpu, denoise set to .5: 4:53

The samples would need to be bumped up on the gpu to get an image equivalent to cpu, but it would still be faster.

Interesting difference in the impact denoise has on rendering time between cpu and gpu.

Does anyone know how the display should be set up if I add a RTX 4000? Which should drive the display, P4000 or RTX 4000?
Title: Re: Keyshot 9
Post by: mattjgerard on November 06, 2019, 05:48:44 am
Shouldn't matter, really. Display output is such a small part of what GPU's do these days computationally speaking, that its not that big of a drain on resources. Years ago, yes, it would matter. But all modern cards have so much horsepower that its all the computational stuff that taxes them, not the display output itself. What might make a difference is the screen resolution. Get too crazy and it does have to calculate all those pixels. I've got 3 monitors plugged in to a n old GTX980 and it shows very little use when using keyshot. I have to sort out the driver issues before I can engage the GPU rendering though I'm not expecting much, as its a pretty powerful CPU workstation.
Title: Re: Keyshot 9
Post by: Prof on November 06, 2019, 02:07:29 pm
I disagree... maybe, because Keyshot will only use 8Gb of the available 16gb of ram on the two cards. So the question becomes what ram is Keyshot using if both cards are enabled?... the GDDR6 on the RTX 4000 or the GDDR5 on the P4000? If Keyshot uses whatever ram it will regardless of which card drives the displays, then you're correct.

I would think that how each card is set in the Nvidia Control Panel... "Dedicated to graphics tasks" or "Use for graphics and compute needs"... would also come into play. Although it makes sense that the later option would be the logical choice for both cards. Anyone?

So... my preliminary findings... i9 9900k, Quadro P4000, ground and global illumination, 100 samples:

Image 1. cpu, no denoise: 4:49
Image 2. gpu, no denoise: 1:28
Image 3. gpu, denoise set to .5: 1:42
Image 4. cpu, denoise set to .5: 4:53

All the GPU renders look bad, right? Even the CPU render with no denoise looks better than the GPU with denoise.

The two are different, output appearance wise. You must set up the shot for either one or the other to get the look and quality you want. The rendering output set up is different as well... the samples must be bumped up 3x - 4x on gpu, but it's still faster depending on the scene and your hardware.

I did few tests too;
I cant post the screenshot because its a confidential machine i was rendering.

Hardware Dual Socket Xeon Workstation E5-2680v4    (28Cores total,  HT deactivated) with 128GB Ram
RTX2070 Super
NW Renderer with 128 Cores total, on 7 Clients.(threadripper,1x old 4 socket 40Core Server, a few Ryzen 2700x Render slaves, dual sockel Xeon workstation) on all slave SMT / HT was deactivated

The Model has 1mio polygons.
It is a 4k image with 1024samples ; Product Mode default Keyshot settings, no special lights, our custom stainless steel material. Default KS enviroment
All Runs with denoise (Slider to 1)

11 Mins for GPU
97 Mins render on the Workstation
32 Mins with NW Render

Edit : I'll get a RTX6000 for testing from our supplier - i'll update my post with additional bechmarks

Why don't you pick models you can post pictures of so we can compare Image quality/difference if any. We all know gpu rendering is faster.
