Any chance of getting a light cache or similar like Vray, Corona, or Redshift? That would drastically reduce render time and seriously improve lighting.

PLEASE no!

Yes it would be horrible to have a better solution for animations.

Already discussed here a lot:

It would drastically reduce quality and seriously make lighting worse; go for V-Ray if that's what you're looking for.

I don't know about reduced quality, I'm not sure if you used other renderers with a lightcache alternative. As for Archviz animation, I might of made the wrong choice with octane, I thought It would be a lot faster, and I'm talking just with it's Biased engine, but it is far from it. Thanks for the link though.

Then you aren't using it correctly. If you post your render settings and what gpu you are using you can get some help.

I'm Using Direct light + Ambient Occlusion, all default settings. Renders the room in 3 min with still noise in certain spots, especially highlights from lights and sun. I have portals in the scene for the windows to help. rendered with a new Titan X Superclocked.

Vray rendered the same scene in 2 minutes with no noise and a few more textured lights, and that's with a i7 3930k.

Seems that with Octane adding the same emissions lights that I had in vray made it take even much longer to get the render noise free.

Some things to try to de-noise renders quicker - pls see the Octane Notes link in my footer (http://poserphysics.blogspot.com.au/201 ... e-faq.html).

For arch interiors I highly recommend using an HDRI and removing walls that aren't in view of the camera. This will speed up your times dramatically. Also, try not to use any really small emitters as Octane doesn't handle them well.

https://vimeo.com/124066262 This is a really great video on optimizing octane.

This is less helpful, but for animations you can get really great results using faster settings and then denoising with something like Neat Video.

if You're into animations then having multiple cards would really help - maybe getting few more cheaper cards like 780s (for like 400$ - each giving You 100 in terms of measured performance in OctaneBench) - 6GB migh be lower than You have on Your X, but speedwise it's a better value (for 30% of price only 30% lower performance =)

2-3 minutes/frame is not so bad with a single card even if it's bit noisy - use some pfograms in post to get rig of it =) or try to optimise Your settings..if You want faster results - sort of realtime, there are other, game engines =) but learning curve of those is way steaper as far as I know..
