Indigo Renderer 2.6.1 Portable | 26 Mb
Indigo Renderer is an unbiased, physically based and photorealistic renderer which simulates the physics of light to achieve near-perfect image realism. With an advanced physical camera model, a super-realistic materials system and the ability to simulate complex lighting situations through Metropolis Light Transport, Indigo Renderer is capable of producing the highest levels of realism demanded by architectural and product visualization.
Indigo is packed with powerful rendering features accessible to Architects, Product Designers, 3D Modelers or artists. Even if you've only been using 3D software for a few days, you can use Indigo to generate realistic renders of your own. Its out-of-the-box materials and lights allow you to concentrate on your designs without spending hours on configuring materials and settings.
