- current release: Redshift 2.6.38 from March 2019
- full integration with 3dsMax, Houdini, Cinema4d, Maya and Softimage
Since April 2019, Redshift is part of Maxon, the company wich creates Cinema4d and other tools.
Redshift is a biased GPU accelerated renderer. Sounds interesting, because most GPU renderers are unbiased. Redshift supports out of core renering what means it can render scenes which do not fit into GPU ram. It has no possibility to develop your own shaders via API but it comes with a good set of builtin shaders like car paint, sss, round corners, hair shader, skin shader and others. It supports non physical lights like point, spot, and directional lights.
- point, direction, spot, area lights
- portal lights
- dome lights
- physical sun and sky
- displacement mapping with auto bump
- geometry and transformation motionblur
- mutliple importance sampling
- open VDB volume rendering
- nested dielectrics
Well, they improved rendering a lot in the last years. Only since January 2019 until April they released 6 minor releases. Hair cann render with min pixel with attribute which helps to reduce noise in hair renderings. It is now possible to render cryptomatte outputs for easier compositing.
Version 2.0 brings open VDB volume rendering, a great step forward. Nested dielectrics are supported, BSDF's are improved with advanced shading models (ggx, beckman). Baking is supported and - really cool - alShaders are supported. This way the useres who use Arnold with alShaders now can switch to Redshift without reshading.
