However, OctaneRender 4.0 does introduce its own spectral AI-based denoising system, described as highly complementary to AI Light.ĪI Denoiser works from “internal perceptual models of material, spectral irradiance and scene data … before to RGB in the viewport”. Unlike Nvidia’s AI-based OptiX 5.0 denoising system, recently integrated into V-Ray Next, it isn’t a post process, but is calculated in real time during the render itself. The second AI-based technology, AI Light, improves sampling, particularly in scenes with many point lights.Īs a machine learning system, its performance “improves as you render more samples”, and it can be used in conjunction with OctaneRender’s existing Adaptive Sampling system.Īccording to Otoy, it makes a “big (6-10x) difference in multi-point/spot light scenes” – presumably in the time taken to resolve the render to an acceptably low noise level. New AI-based light sampling and spectral denoising systems The division of scene assets between in-core and out-of-core memory is handled by the first of the new AI-based technologies that Otoy has just announced: the AI Scene system.Īccording to Otoy, the system models the visibility of surfaces within the scene on a per-view basis to maintain optimum performance for out-of-core-geometry. The demo video above shows a “worst case scenario” of a 40GB scene being handled entirely as out-of-core geometry, with the scene still maintaining a steady frame rate of 60fps. There is also a new system for handling out-of-core geometry, making it possible to render scenes too large to fit into available GPU memory without the speed hit usually associated with the process.
OCTANE RENDER 3 RELEASE DATE UPDATE
Otoy claims that scenes load up to 10x faster than in version 3.x, and update up to 100x faster – a “night and day difference” that makes it possible to scrub through FBX and Alembic animations in real time.ĪI Scene juggles scene geometry between GPU and out-of-core memory The integration, which gives OctaneRender a new “game-engine-like scene graph”, promises considerable speed boosts. Integration of the Brigade engine, major speed boosts to scene loading and updatingįirst up, the major feature we already knew about: version 4.0 integrates Brigade, Otoy’s real-time path tracing engine – itself a work in progress for over five years – into OctaneRender.
