Hello everyone !
Happy to post my first message here !
i've been seeing some really great stuff about octane workflow and would like to give it a try
in a new workflow.
As my mac crashed a few days ago i'm considering buying a PC.
I'm using vray with cinema4d.
Vray version 1.2 for c4d is not yet configurable for gpu renderings as version 2 for maya.
so i'll still be under a wait and see process even if my next machine would touch 22 on cinebench cpu score.
My wish is to use octane for previz in order to quickly define lights materials camera angle, having a look of what i want to see
the quicker and better possible way.
Once the look match my desire (and the ones of my client) i'd get into vray with the octane renders as reference.
This process means doing again things like lights and materials inside vray i know.
But having a good reference is key and gpu based rendering can masters this quickly.
And i could anyway continue with octane for final delivery.
Questions :
Is there anyone here having testing this workflow ? (octane for previz and vray for final renderings)
i'd like to hear about his feedback !
(is it easy to match an octane render inside vray / will camera match / are there plugins on the market that
translate an octane scene into a vray scene / etc.
As i'm coming from mac machines, i'm not that used to define hardware specs for my needs :
considering a geo force 680 for system and app and a geforce 690 for gpu octane's calculations, (sli)
is it a good option ?
I thank you very much,
cheers,
arnaud.
looking for feedback users : octane + vray

Can i put 2 geforce 590 + a basic graphic card in a pc ?
(as 600 series are not handled)
what kind of mother board is best for this ?
thanks !

=) hi there!
I see no need to mess with octane if You using Vray for final result =) VrayRT does have (at elast on 3dsMax) GPU render engine integrated that basically as fast as Octane. Technicaly it is ment for previews, when Octane is pushing as production render engine (not only for previews) at the very moment You simply can't compare those side by side, as OR is very Young, while Vray is mature enough (10+ years of development =)
If I were You I would stick to VRAY + RT option - in that case You will not need to convert mats, reDo the scene lighting etc.. - and that might be time consuming =)
but! I would actually buy a licence of Octane ant try it - it matures quicly & I wouldn't be surprised to see it among the strongest render engines soon =) if You will have a GPU, why not to learn one more way to utilise it's power? =)
as for MotherBoard..it depends on Your budget and Your needs.The most simple is to combine lowEnd (or very small hiEnd motherboard) and something like 690 - if You need speed, or 680 if You need most vRam (to be able to handle bigger scenes) If You got more money - motherboard with 3-4 pciE slots are available =).. pick the one You like depending on your needs (they can differ by features and price..a lot =)
now some last but not least fact =) Octane has voxelization process that is quite RAM hungry, so if You put let's say 4gb gtx680, make sure You have something like 16GB of RAM =) other things is that voxelisation is single threaded, so..faster Your CPU, faster You get the output =) if You're going to do animations..having some high runnin' OC'ed CPU (like 3770k @4.5+ is advisable =)
if You got money You can put 8gpu cards if You want - it depends on Your budget =) & other priorities..like conectability, onboard options, OverClockability and so on..

Hi,
I'm trying to collaborate with Otoy, Chaos, RC programmers giving them my feedback.
If you need to render master plans or multi pass complex animations you will use Vray because the other valid option is Renderman + Maya.
For hyper realistic still renders the best option today is Octane for Max and Maya.
Unfortunately these rendering engines now lack many features that we found in cpu based rendering kernels.
Broadcast and cg special fx world tends to minimize the post production pipeline.
Now with gpus we can have a full integrated pipeline for rendering and compositing.
If you look at the most important cg web sites you will notice that the 99% of renders are made with vray.
CPU render needs a cheap workstation, gpu render wants a lot of power and expensive hardware.
Btw, gpu render it's the future of rendering.

quad Titan Kepler 6GB + quad Titan X Pascal 12GB + quad GTX1080 8GB + dual GTX1080Ti 11GB
it depends from what perspective You're looking at things..if You want to get good render times out from CPU render engine having something like dual chip Xeons with 8cores each.. - that isn't going to be cheap at any means..even having high-end 6core desktop parts might set You back for 1k$ CPU only..gabrielefx wrote: CPU render needs a cheap workstation, gpu render wants a lot of power and expensive hardware.
So in this case comparing prices CPU versus GPU rendering is kind a slippery thing..- try to mach something like Octane's output speed on GPU with Maxwell-Render's running on CPU - You will spend way more building render farm..(some might say that You get more for Your money too =)
And it may run circles aroun octane in interiors, just sayin...glimpse wrote:it depends from what perspective You're looking at things..if You want to get good render times out from CPU render engine having something like dual chip Xeons with 8cores each.. - that isn't going to be cheap at any means..even having high-end 6core desktop parts might set You back for 1k$ CPU only..gabrielefx wrote: CPU render needs a cheap workstation, gpu render wants a lot of power and expensive hardware.

Thanks a lot for all your good answers, things are getting more precise, thanks to your feedback.
For now i'm using vray for cinema 4d that means we're not into RT nor gpu stuff fnow, inside vray, that's why i want to give a look at octane.
And the time to develop vrayforc4d from 1.2 (actual version) to 2.0 is impossible to guess as for the version 1.2 to 1.5 was a question of days or few weeks to get on the market, some 8 months ago.
Concerning cinema 4d we're lacking a good up to date render solution both for vray and octane plugin.
Coming from the mac world since 10+ years, going to PC world with diy choosing component parts in your machine is a long process.
Coming from vray 1.2 with multipass not that effective, i'm used to combine different renders from vray and the internal render engine of c4d /
Going to octane i can't even install on my laptop is a bit risky but seems like the killer solution for my work : mostly tv ads where time for production are very teady/
From my point of research at this moment : octane needs the strongest machine and for the same rendering time vray needs more than one machine : renderfarm.
The wait and see buckets process inside vray 1.2 compared to octane bit grainy but instantly is having a choice already made between those two engines.
Now comes the process of voxellisation which is not strongly effective with c4d.
To synthesise it is not the right moment to buy a new workstation for me ; unfortunately i have no choice, (station crashed few days ago).
Help me confirm / answer these questions or facts :
in octane :
1 / Graphic cards
- The graphics cards need to be the same for best performance but they can be different for octane to work
- The 600's series are 10 to 20% slower but have more Vram than the 580 which is hard to find nowadays / developpers are on their way to adapt octane with those 600 cards
- The vram of the GPU ? huh ! what is that used for ?
2 / CPU :
- Process of voxellisation is non multicpu enabled
- The speed process of voxellisation depends on the clock of the cpu not on the number of cores it has
3 / RAM
- The RAM is used for textures visualisation 16 Go by graphic card is best suited with 8 Go units
4 / COOLING + EXTERNAL GPUs
- Apart rom the power needed there's a need for cooling strategy as GC can be hot very often and quickly :
With vray we can let a render work for one week but for GPU renderings the temperature needs to be monitored that would mean : being glued to the computer while it renders ! ?
> Are there external solutions that can let you push the render button and then get back home with no stress ? is cubix the rightly cooled choice for that ?
- In an external gpus solution like cubix can we put one single card in a 2 product cards available slots ? can we put 2 cards in a 4 product available slots ?
As for RAM where they need to work two by two : do we have to put two GPU cards the same kind two by two, or do they need to be all the same specs for best performance ?
5 / CLOUD RENDERING
- I imagine cloud GPU rendering as a laborous process as the .obj sequence can be very heavy to send to a ftp : let's say we could have a 1 Go a frame to send sometimes,
meaning 24,25 or 30 Go a second.
Where can i have the process for cloud computing explained ?
I thank you very much,
Have a good one,
PS: sorry for this big message and for bad english here and there, i'm french.
