Octane Render is an unbiased rendering application with real-time capability. It was created by New Zealand-based company Refractive Software, Ltd., which was acquired by OTOY on 13 March 2012. Version 1.0 was released on 28 November 2012; later versions of Octane Render continue to be deployed using Web release. Octane render was the first commercially available unbiased raytracer that fully utilized the GPU, giving it a significant speed advantage; this allows users to more easily modify scenes in real time.
Octane Render runs exclusively on Nvidia's CUDA technology, restricting it to Nvidia video cards; Octane Render 2019 is planned to run on Vulkan and therefore will be able to run on both AMD and Nvidia graphics cards.
