Indigo Renderer

Indigo Renderer is an unbiased, photorealistic GPU and CPU renderer that simulates the physics of light to produce photorealistic images. It uses spectral light computations, physically-based materials, and accurate camera models, offering an interactive, photographic workflow with few abstract settings. It is developed by Glare Technologies Limited.

The renderer includes a multi-GPU OpenCL engine supporting Nvidia and AMD cards on Windows, OS X, and Linux, alongside multithreaded CPU rendering. Features include denoising, lightmap baking, GPU subsurface scattering, Light Layers for editing lighting without re-rendering, a sun and sky system, section planes, orthographic and spherical cameras, subdivision and displacement, IES lighting, alpha output and shadow-catcher compositing, animation and render queue support, and network rendering with a Network Manager. Plugins are available for Cinema 4D, SketchUp, 3ds Max, Blender, and Revit, and an SDK with a C++ interface allows integration into other applications.

Indigo is offered as Indigo Renderer and Indigo RT editions, with a free trial available. Network and floating licenses are supported, and the SDK can be used with watermarking or with a licence key; developers can resell Indigo licences to their users.
