Indigo Renderer is a Windows software for rendering 3D objects created in Blender, Autodesk 3ds Max, SketchUp and other popular programs. There is a powerful GPU engine for faster processing of high resolution models. It is important to mention that the free trial version of Indigo Renderer will stop working 30 days after installation.

Light simulation

Users can accurately imitate sun rays and other lighting effects to produce natural looking renders. This is achieved by complex spectral calculations instead of drawing classic RGB points. It is possible to adjust the color temperature and brightness of the scene without re-rendering.

There is an advanced sun and sky system based on realistic atmospheric simulation. You are able to produce natural weather conditions as well.

Materials

A large library of physically-based textures is included. These materials interact naturally with all light sources to deliver the best results. Subsurface scattering can be emulated accurately for extremely lifelike rendering of skin, leaves, wax and other dense objects.
