Re: Redshift - GPU accel on Quadro K4000
Just an fyi, the quadro k4000 is around 4 times slower than a 780 gtx for redshift rendering...

You probably won't have to re-plug any nodes, unless you used bump or displacement. There are some differences, but as I said before, not many.

Re: Redshift - GPU accel on Quadro K4000
Yeah, if you're on time for a return it might be worth considering. The K4K isn't great bang for buck, it has a massive quadro label overhead to the price and it's not really that well featured. I don't know if 4x is an actual measure of the difference, I don't have both cards at hand to test nor redshift, but it's openly underspecced.
Re: Redshift - GPU accel on Quadro K4000
I've both cards and the 780 seems to be round about 3 times faster than the quadro when rendering with redshift.
Re: Redshift - GPU accel on Quadro K4000
What really speeds up Redshift is VRAM on the graphicsCard to avoid slow PCIe Traffic... 4GB and more makes a big difference. I select my cards with this priorities: 1. VRAM 2. GPU-Cores 3. Mhz 4. ... Good idea is a second card only for rendering: no memory used for display stuff, complete VRAM for Rendering... BTW: They are just out with the V1! Regards Stephan I've both cards and the 780 seems to be round about 3 times faster than the quadro when rendering with redshift.
Re: Redshift - GPU accel on Quadro K4000
Just double checked my test figures and it is more like 3 times, sorry for the confusion. This is on an indoor environment with a single character with hair, GI and DoF. On heavier environments/multiple characters the titan really shines. 2 quadro k4000 - 284.8 s quadro k4000 - 509.7 s Titan - 146.8 s GTX 780- 172.5 s On 2 April 2014 09:59, Tim Borgmann i...@bt-3d.de wrote: I've both cards and the 780 seems to be round about 3 times faster than the quadro when rendering with redshift. -- www.matinai.com
Re: Redshift - GPU accel on Quadro K4000
I have a Quadro 4000 and this has been discussed other Redshift forum. It's not bad for Open GL working, but defenetly not for rendering Quadro 4000 has around 400 cores while Titan has around 3000 cores. Also comes the Memory 2Gb against 6Gb, and I can't tell for the Mhz but overall it doesnt compare at all. According to the RS team you could expect the Titan to be at least 3 or 4 time faster than Quadro 4000 Le 02/04/2014 09:13, Raffaele Fragapane a écrit : Yeah, if you're on time for a return it might be worth considering.

Re: Redshift - GPU accel on Quadro K4000
If you can wait (and have slightly deeper pockets) the 780 6Gb will be out at the end of april - shouldn't be that much more expensive than the 780 according to early reports. That will be the best bang for buck card for RS, as the memory will really help with larger scenes. -- www.matinai.com

Redshift - GPU accel on Quadro K4000
Hello everyone. I´ve been recommended -not enough through :) - that I switch to Redshift render. So finally I upgraded my Quadro card to K4000. Up until now, I´m very very very much impressed with MODO 3D (my 3d package of transition) and results are astonishing. I can almost feel the Realtime engines like Crytek or UDK for PS4. So being our software of preference, I´m trying to pick up a GPU renderer (Redshift) in softimage. One thing I´m trying to wrap my head around it´s the entire rebuild connectivity of materials for redshift. So if anyone, please, has a blog or an article to share to strat up my baby steps on using Redshift I´d appreciate it deeply thankful to help me out with that. Cheers.

Re: Redshift - GPU accel on Quadro K4000
There are only a handful of specific nodes that are unique to Redshift3D. Everything else is exactly like you are used to in the Materials (nodes) in Softimage. They did a great job making it almost seamless a unique example... if you want to bumpmap some object, you would select the Redshift bumpmap node, instead of the regular mentalray bumpmap node. That is one of the nodes that is specific to Redshift. And you would plug the outpuit directly into the Material input, not the shader. On the pass, or scene, you specify the Redshift render instead of Mentalray and you also need to adjust the render settings. The default gamma is set to 2.2, and in most cases you should change that to 1.0. Other than that, the options are very similar to what you are used to with Sorry for the rambling description instead of a decent tutorial, but they are working on a set of tutorials right now, and should be available soon. You will not take long to adapt to this, I found it extremely easy to use. The docs http://docs.redshift3d.com/Default.html are very complete.
