OctaneRender is a GPU render engine that OTOY describes as unbiased and spectrally correct. It supports physically based spectral light transport, multiple GPUs, network and volume rendering, and out-of-core textures. Its interactive viewport updates when scene settings change; OTOY says the on-screen view is the final render. Material features include Open Shading Language, procedural materials, complex PBR textures, toon shading, and the OctaneLive material database. OTOY lists more than 21 plugins, including Blender, Cinema 4D, Maya, Houdini, Nuke, and SketchUp, and the.ORBX format supports scene interchange between supported modeling tools. The free Prime tier permits personal and commercial use, with a one-GPU limit and no network rendering. Studio+ costs €19.99 a month billed yearly or €23.95 a month billed monthly, and has a default maximum of 10 render nodes. Windows and Linux require a CUDA 10-capable NVIDIA graphics card; Octane X 2023 and later requires Apple M1 or newer GPUs with macOS 14 or later.
