Will evolve over many releases, but already makes a 6x-10x difference in multi-point/spot light scenesĪI denoiser is doing spectral floating point banners per wave length, per beauty pass before tone mapping or RGB rendering to viewport - very hard to top in a post-processing denoiser. AI Light is done in the renderer, fully unbiased, and tracks emissive points in real time. It can dramatically cut down on light sampling time, especially in scenes that have many localized spot lights. It doesn't 'cheat', but looks at the scene before casting any rays and intelligently picks which rays to render. If it's something that's out of the viewport, it gets cached differently.ĪI Light is a learning system that improves as you render more samples. Through heuristics & intelligent tracking of topology, it can pull data in and out of core and determine the optimal configuration between system RAM and VRAM (e.g., 85% and 15%) to make the ray/path tracing faster. Scene AI technology brings interactive positioning and modifying of geometry in real time, even in scenes with several millions of triangles. You can now use use a significant portion of your system memory (as opposed to VRAM) for geometry data! In one stress test, OTOY tested the worst-case scenario of no assets in GPU memory (0 Kb VRAM used) and 40 GB+ geometry in CPU memory - moving objects in the viewport was still interactive, at 60+ fps to boot! Multiple GPUs are also supported: in one test, OOC geometry scaled to 8x Volta GPUs + 150GB of scene geometry in CPU RAM. The new file cache system in v4 will help remove the GPU memory load time bottleneck after first load of large geometry. The larger the object, the slower it was to move it almost like the inverse square law of mass.
And because of the output buffer’s location in the system RAM, you had to constantly shuffle scene data back and forth on the PCIe bus to synchronize the passes between multiple GPUs. However, the geometry was still confined to the VRAM. On Octane 3, when texture data would fill up the VRAM, parts of it could be moved to system RAM.
Here's the really exciting breakthrough for RNDR miners - out-of-core (OOC) geometry! This comes back to the 10x faster scene loading. More about this in 'AI Light + denoiser' below. This can greatly lower the requirements for reaching real time photorealism in the near future. An insanely interesting topic in its own right, it's a technique whereby Machine Learning algorithms, having been trained by millions of noisy/final render example pairs, essentially 'dream up' the correct image from having learned to generalize for novel data. Looking at the raw specs, in the five years since then we have gone from 2,688 CUDA (Kepler) to 5,120 CUDA (Volta), or a factor 3x increase in perf/watt.įast, but still not fast enough for real-time, and this is where AI denoising comes in.
#Octane render 4 unity 1080p
It was running at 1080p / 25fps, relatively low noise on a couple of NVIDIA (Kepler) Titans - completely unheard of at the time. We saw little glimpses of it over the years, like this interior scene from 2013 being done on Brigade using unidirectional path tracing. For the uninitiated, Brigade was OTOY's first foray into the realm of real-time rendering. The day that many of us have been waiting for is finally here: The merging of Octane + Brigade into Octane Render 4. Scene changes 100x faster than v3 (moving heavy objects often 60+ fps ( 2m07s) Scene loading 10x faster than v3 (practically instant) Octane 4 integrates all of Brigade, Octane's real-time pathtracerġ00% new scene graph, feels like a game engine!
#Octane render 4 unity update
Free Tier users can update to Pro/Enterprise via RNDR work, an example of the 'RNDR It Forward' concept first proposed by daffy_ch. Yet, the biggest growth will no doubt occur in the Prime/Free category, bringing tens of thousands of new users to the ecosystem and further increasing the potential demand from content creators. Octane 4 upgrades all v3 customers free of charge, so those categories will have a lot more users right off the bat. The 20,000/200,000 OB/Hr limits on Subscription/Enterprise will enable massive render jobs to be sent to the network. With any of these licenses, you will be able to launch ORC/RNDR jobs starting from the equivalent of running 2,000 OB per hour (~10x 1080 Ti's) on Prime/Free, up to 200,000 OB per hour (~1,000x 1080 Ti's) on Enterprise.
