Photorealism Test : Vray vs Octane (side by side images!)
So I've been playing around with Octane trying to make it render more realistically than V-Ray. Identical scene, same lighting setup (plane lights in windows), same materials, (edited) Vray using ... (won't tell you)
The results are quite spectacular! I'd actually like to ask everyone, if they can tell, which images belongs to which rendering engine? =)
Fire away, don't be shy! Which is V-Ray and which is Octane? Left or Right?

(it will be interesting, to read the answers..)

Haha. Really like your topic. Should get more in this forum.
But did you say Vray in left hand side already in your post?
Anyway, I like the right hand side picture. Any idea how long they take respectively?

Octane is left, VRay is right.
Neither look photoreal to me.

@Scottiefeng V-ray image took 6 minutes total on my home renderfarm, which consists of (3) machines, x1 3930k @4.2 GHz, x1 Xeon x5650 (24 thread), and x1 Laptop 4700MQ processor, all machines using Intel EMBREE Raytracer, which improves V-Ray rendertimes by about 30% just by enabling Embree (!!)
Octane render took 1 hour 20 minutes on 2x GTX780s 3GB, 16000 samples, PMC, Octane Plane Lights at the Windows, OctaneSun outside, 3dsmax plugin. It definitely took a loooong time, but in my opinion, Octane has better light propagation and better reflections. Though V-Ray produces less noisy results in far less time.
V-Ray however, for the speed/quality, is pretty much unbeatable I would think, for now.. However it will be interesting to read the experts on Octane Render, what they have to say about why Octane produces more photorealistic results than V-Ray. In my opinion, Octane is superior (we all know it is), but they are both very capable render engines. Any Octane experts are welcome to explain to us why it produces simply more realistic lighting results? =) Unbiased is the future, undoubtedly.
But... I'm still not saying which image is which renderer

.. I want to Pros to post below!

Hi interesting topic. Octane is on the left i bet. i m not defanding Octane but this competion didnt seem like fair to me. beside the hardware, experience makes sense also. hıw long have you been using Octane and Vray?

Octane left, VRay right.

@Sadece : This was no competition, I was just bored on Sunday night and decided to run this little test to try and see the benefits of Octane. I know there are some truly pro-level users here who would put these images to shame, I am far from a pro!
To answer your questions, I have been using V-Ray for about 6 years, Octane, about 1 year on and off, learning and testing. There's not many tutorials on Octane for 3dsmax around so I have learned on trial and error and reading the forums here. V-ray there is tons of learning material.
@face_off : Correct! I would expect nothing less from an Octane Developer.
I would actually like feedback on where 3dsmax plugin users can find great tutorials for Interior Rendering? Any feedback would be appreciated to improve the technique, specially on Octane Lights and Sampling / controlling Noise levels without 20,000 samples (zzz, zzzz..), I've read some artists use Noise Reduction plugins (Neat Image) in Photoshop?

It's all a matter of settings, bounces etc. PMC is completely overkill here.
I can highly recommend the tutorials from Kevin Shane:

Hey Charles!
Dude! dont compare a screwdriver with a hammer! one is good for screws, the other performs better with nails! interiors in productionquality and large sizes are much easier to compute with bias since there is much interpolations going on which leads to a clean and smooth result in acceptable rendertime. set vray to bruteforce/bruteforce, and raise subdivs till you get a clean and smooth image.... what you will see it that vray looses all of its speed then

all i want to say is: vray performs excellent when it comes to big scenes with much computations and when you know how it can help you to focus all the renderpower to those spots where its needed most. BUT: when precision is the focus and you got scenes where you got less to compute but want highest quality then octane would be my first choice. I would not realy try to render an interior with much detail in an real closed room with much much indirect light with octane PMC or even pathtracing on a single Titan or two.
I also think unbias is the future, you see more and more renderers without bias out on the market right know - and the computing power gets cheaper and cheaper. bright future for renders but also hard times will come for technical professionals. if you imagine renderpower will raise further with that speed rendering will be technical easy like switch on a torch. just press render and let the light behave like light behaves. artistic skills will raise in value and vray professionals will sit in rocking chairs with cups of tea and talking about good old rendertimes, where rendering was a matter of professionals who had to fight technical issiues depending on certain circumstances depending on motives.

product viz is already that far, compared to the technical challenge controlling the bias of vray is octane a simple button with "render" written on.
