Indigo Renderer is an unbiased, photorealistic GPU and CPU renderer aimed at ultimate image quality, by accurately simulating the physics of light. State of the art rendering performance, materials and cameras models - it's all made simple through an interactive, photographic approach
with few abstract settings, letting you concentrate on lighting and composing your imagery.

Indigo Renderer 4.4

We are proud to announce the official release of Indigo Renderer 4.4.
Indigo 4.4 brings denoising, a fabric material, GPU SSS, lightmap baking and more.

What's new in Indigo 4?

Brand new multi-GPU engine

Indigo's OpenCL-based GPU engine provides industry leading performance on Nvidia and AMD graphics cards. With a single modern GPU, it's approximately 10x faster than before. Simply add more GPUs and get the horsepower to quickly render incredible 4K images and animations.


Workflow & UI enhancements

A dark UI mode. Interactive material previews and light layer thumbnails. RGB colour curves and snappy trackball navigation.

These are just some of the new features making Indigo 4 the most streamlined and enjoyable version yet.

The rendering quality is awesome, and it's so fast than I can set up scene lighting with our technical art director about seven times faster than with our other render engine
Mateusz Sroka, Platige Image
Indigo is usually my go-to renderer: it handles massive scenes very well. It loads fast, it's reliable, doesn't crash and produces beautiful results
Tom Svilans, architect


"We simply love the lighting and the realistic look. Without the need of tweaking and faking light situations or GI render settings, Indigo simply renders it as it is... and so we can fully concentrate on color grading and subtle post production. Almost like you would do it with real filmed footage."

- David Gudelius, Senior CGI Artist


"... 35K objects, 201 million polygons, 804 light sources and hundreds of materials. Indigo crunched through this data without issues and allowed a workflow with quick previews and great output quality without tweaking 1001 settings like in some other renderers. With this reliability I could focus on content creation and tweaking material in the project."

- Arthur Liebnau, Freelance CGI artist

Atmospheric scattering tests

Over here at Indigo HQ, we have been doing some more experiments and optimisation of our atmospheric scattering code. Each of these scenes have a single light source - the Sun. The colour of the sky results from the light scattering off the atmosphere's air molecules and water droplets. Since b...
