OTOY Forums

Hey all!
This is my first post here!
I am new user Octane (3ds max).
The image is in DL + AO because I only have a GTX 580.
I've seen many images taken with DL + AO on this forum, which looks very good.
That's the reason I bought the program ... speed!
Any advice for improving the image is welcome.
Thank you!

first thing first...

Your glare is wayyyyy too strong, turn that down.

now, a really good way to reduce noise, is to open up some walls that arnt seen in the image. try that.

Seems your emitters are producingthe noise.
Is the lamp a emmissive texture? Or is there a octane-light within the glowing lamps?
How many samples you are using?

I see that you only have one graphic card yet you claim you bought program becasue of the speed. How much does it take to render this sort of sceen?
I was thinking that you need at least 4 graphic cards to get some deecent rendering time with Octane. Am I wrong?

I suspect it's because the large dangly things are your emitters? Probably too much 'geometry' in them to do that, might need to reduce their face count

If it's a single view, then I'd hide the wall behind the camera, to get some ambient light in, could just use a white-ish colour or a neutral-ish HDRI to illuminate the scene, could even render this PMC, 5000 maxsamples or whatever

personally, I'd model the floor, easy enough to instance, could use a bit of maxScript to lift each tile up 2mm or so, up and down randomly

- select all the floor tiles and then type this in your maxScript listener - for i in $ do i.pos.z += (random 0.002 -0.002) - and then hit return, assuming your units and system units are metres....

and then I'd then consider rendering the feature lights separately, so one render with just ambient white light, another with a black texture environment and this time with the emitters on, and even rendered half res, direct lighting or path-tracing, and then this overlaid in photoshop, screen or linear dodge/add

Thank you all for advice.
Here's what came out!

Consider using Lightroom's luminance based noise reduction. I found it works very well with Octane's renders. It is not magical of course but it does wonders with no undesired blur.

PS: You are in luck. All I have is a gtx 560ti.
