Real-time 3D Rendering
The world’s first GPU-based,
physically correct renderer.

About OctaneRender®

OctaneRender® is the world’s first and fastest unbiased, spectrally correct GPU render engine, delivering quality and speed unrivaled by any production renderer on the market.

OTOY® is proud to advance the state of the art once again with the release of OctaneRender 4™ – available now – with groundbreaking machine learning techniques, out of core geometry support and massive 10-100x speed gains in the scene graph.


What’s New in OctaneRender 4™


  • Brigade Engine Integration
    OTOY’s real-time path-tracing game engine ‘Brigade’ has been integrated into OctaneRender 4, making heavy scene loading and interactivity up to 10x to 100x faster. Brigade gives artists instant game-engine like feedback in the Octane viewport while moving or deforming heavy meshes with millions of triangles.
  • Out-of-Core Geometry
    OctaneRender 4 can render fast out-of-core geometry entirely from CPU memory, with minimal speed loss and viewport lag (even across multiple GPUs) – a first for an unbiased GPU renderer.
  • AI Light
    Accelerates light sampling, tracking emissive points in real-time with up to 6-10x speed gains in scenes with many small light sources such as multi-point or spot lights.
  • Spectral AI Denoiser
    OctaneRender 4 introduces groundbreaking machine learning technology to interactively denoise beauty and AOV passes on-the-fly, both in the viewport and for final frame production rendering.

    Unlike other post-processing denoisers, the Spectral AI denoiser operates on internal perceptual models and scene data deep in the engine. Domain specific AI denoisers help with volumetrics, glass, refractions, SSS, depth of field and motion blur, reducing render times by 50-100x in noisy scenes.
