Octan render speed

Hello,

I have question about speed of octane render. In future will be some speed improvements?
Because I want to use octane in production, but render time is too long (DL is not very usable).

Corona render has more render modes (PT+PT or PT+HD cache - really faster than PT+PT) but is only for CPU;
(embree has lower noise as GPU rendering)

I need to produce 3500x resolution interiors in max 20 minuts. How many GPU (780 ti for example) I need for this in octane render?

Thank you for your answer!

Lukas

Just wait for Octane CE to come out, that will solve your problem. ;)

Octane CE ? What's that ? do you have more info/links to that.

Thanks

On topic
lukashanku - what GPU(S) you have now and what's your current rendertime ?

Octane Cloud Edition, there are plenty of topics in this forum about it. ;)

Interiors and multi bounce indoor scenes will always be slow with pathtracing bruteforce.
You can only speed it up with raw power which means adding more gfx cards.

20min for that resolutions is hardly doable even with 4Titan Black,
if You want to throw complex materials, nice lighting, etc.
unless You get into serious optimisations & use efficient lighting..

it's not impossible, but..You'll always have same noise or some scenes might be impossible to render.
If You're good with HDR making & have fair understanding of basics, You can try to mimic..
something like open case scenarios where You have like floor, wall & the object of interest (not entirely closed rooms)
To make this believable You'd better create good environment maps. This is the fastest way to get good results.

OR ir a pathtracer & interiors are not the fastest thing to calculate =)

OCE is surely going to help & would advise to get good card or two (like 780 6gb) for previews & subscribe for CLOUD once it's available. You'll pay only for time as You need it - no need for big investments etc. Two 780 is enough power to get reasonably fast previews & fit bigger scenes.

What's your hurry :) ? Just wondering if that's an arbitrary deadline or if something specific is driving it, because you'll need quite a physical investment in GPUs to get that kind of render time for interiors. Are you currently using Corona to achieve this?

No prob to render much quicker with Octane, but for sure good investments needed. With 'GPUBox Artist' it is possiable to make a farm of Linux-based multi-GPU slaves and connect them via 10Gbit LAN with your main System, and your OperatingSystem will count all those GPU's as installed directly into your own system. This way you'l get the result at superman's speed;D
