Maxon's Redshift GPU renderer offers AI-based denoising options — including NVIDIA's OptiX and Intel's Open Image Denoise (OIDN) — that use deep learning to remove noise from 3D renders, allowing artists to use fewer render samples and get cleaner results faster. As of Redshift 2025.2 (December 2024), OIDN 2.3 became the default denoiser, with GPU-accelerated support across NVIDIA, AMD, and Apple Silicon hardware.

OptiX and OIDN are described in Maxon's official documentation as denoisers that 'use deep learning algorithms that have been trained with tens of thousands of images.' They analyze a partially rendered image and produce a cleaned version without requiring additional render passes. Redshift also supports a traditional non-AI denoiser (Altus). The AI denoisers are available to all Redshift users across supported host applications including Cinema 4D, Houdini, Maya, Blender, and 3ds Max. GPU-accelerated denoising across all major hardware platforms was standardized in Redshift 2025.2, released December 2024.
