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 4.2
6 Dec 2019
We are pround to announce the official release of Indigo Renderer 4.2.
Indigo 4.2 brings render channels, GPU rendering speedups, CPU rendering improvements and much more.
Read about it (and check out the Indigo 4.4 beta details) here.
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. READ MORE
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. READ MORE
And a lot more ...
RGB colour curves
Interactive multi-region rendering
Light Layer thumbnails
Faster CPU Rendering
Queue override settings
Measured BRDF support
Interactive aperture controls
Pixel info picker
Adjustable light sampling
OpenEXR output settings
Improved MLT rendering
Optimised material models
Faster subdiv & displacement
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 READ MORE
"... 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."

Sloppy coating material
This material uses the world-space normal and the curvature of the surface to simulate a sloppy paint job.
The world-space normal is used to simulate paint only sticking to the top and bottom facing surfaces.
The curvature is simulating paint sticking in crevices on the surface.
You can f...READ MORE

The Cosmonaut by aleksandera
Indigo user aleksandera created this beautiful piece, inspired by Jeremy Gedde's paintings, for the recent Indigo 3.6 competition; however, his final version unfortunately didn't meet the deadline, and since it's such a good showcase image we'd like to feature it here.
Here is his finished work, ...READ MORE

More bidir optimisations
A little while ago (1st december last year) I wrote that I had achieved a 20% speedup of bidir (bidirectional path tracing) on a reference test scene, measured relative to our last stable release, 3.6.
Since then I've been continuing to optimise bidir and the indigo render core in general. Indi...READ MORE

Following on from the last blog post about Atmospheric and volume rendering improvements in Indigo, here's a render using procedural clouds and Indigo's atmospheric simulation.
This scene (or an improved version) will probably be bundled as one of the example scenes for the next Indigo version...READ MORE
