Otoy has released OctaneRender 4.0, the long-awaited update to its GPU production renderer. The release integrates Brigade, Otoy’s real-time path tracing engine, into OctaneRender, speeds up scene updates by up to 100x, and introduces intriguing new AI-based lighting and denoising systems.

Otoy has also announced that the software will be free to use on two GPUs, including access to 12 of the company’s integration plugins for DCC applications

New Features of V4:

– AI Light
With the introduction of AI Light in Octane, you will see a great improvement in light sampling, especially in scenes that have many lights with localised distributions. As a learning system, AI Light improves as you render more samples. When used with Adaptive Sampling, AI Light gets even better, since it will learn that other lights become more important, as some pixels are no longer sampled.
– AI Scene
AI Scene in Octane brings you much faster scene loading times, and a dramatic improvement in viewport interactivity. You are able to position and modify geometry in real time, even in scenes with several millions of triangles. Vertex animation with constant topology is updated in real time in complex scenes, as you move the time slider. Using the gizmos in the viewport on massive scenes is also in real time.
– AI Denoiser
The much anticipated Spectral AI Denoiser allows you to render noise-free in a fraction of the time. You will find the settings to enable it in the Camera Imager settings.
– Out of core geometry
Octane now supports out of core geometry, allowing you to use a significant portion of your system memory for geometry data. Multiple GPUs are also supported with out of core geometry. In your preferences, you will see four sliders under Out-of-core. System RAM usage limit allows you to limit how much system memory Octane will use for out of core geometry and textures. Geometry data GPU RAM usage limit allows you to specify a limit on how much GPU VRAM you want to use for geometry, and underneath, you can set the same for textures. This allows you to balance the level to which textures relative to geometry are evicted from VRAM.
