OTOY has announced the official release of OctaneRender 4 with Brigade integration, out of core memory support and more.

Brigade is Otoy’s real-time ray tracing game engine. It’s now integrated into Octane 4 with promises of scene loading and interactivity improvements of 10 – 100x. Alongside this, Octane now allows out of core geometry using the CPU memory. According to Otoy “All meshes and textures can, if desired, be stored in CPU memory while Octane is rendering at fully interactive speeds with no viewport latency. Scene AI models visibility of surfaces in real time to dynamically move geometry in and out of core for maximum performance.”

A new Spectral Denoiser is included that uses machine learning technology to interactively denoise beauty and AOV passes on-the-fly, both in the viewport and for final frame production rendering. Otoy explains that the technology works on “internal perceptual models of material, spectral irradiance and scene data deep in the engine. Domain-specific AI denoisers help with glass, refractions, SSS, depth of field and motion blur, reducing render times by 50-100x in noisy scenes”. There also a separate Volumetric AI Denoiser for removing noise in volumes.

Continuing on the AI theme, a new AI Light is included that “is fully unbiased, and tracks emissive points live, in real-time with up to 6-10x speed improvements for scenes with many small light sources such as multi-point or spotlights.”

There are plenty of other improvements too, including light linking and light exclusion, a planetary environment system, a new universal uber material, 25% speed gains in raw OctaneBench performance for shading and lighting, native Substance PBR texture integration, support for UDIM textures, 8:1 GPU texture compression, IOR texture input for materials, multi-layer OpenEXR import/export, a new FBX scene exporter node and more.

This release also introduces Octane 4 annual ‘all-access’ subscription plans. These start at $19.95 month with a 1-year minimum period and provide access to all the integrated DCC plugins including Maya, Cinema 4D, AutoCad, Revit, Houdini, Blender, 3ds Max, After Effects, Nuke, Unity, and soon, Unreal Engine.
