Arion 2.4’s LightMixer layers in action. The render layers can be generated alongside the regular unbiased render without increasing calculation time, making it possible to relight a shot in a compositing package.

RandomControl has posted some new sneak previews of Arion 2.4, the forthcoming update to its physically based hybrid CPU/GPU renderer – including some interesting relighting features.

Version 2.4 of the software will make it possible to output up to 10 LightMixer layers (above) to a multi-layered EXR file, making it possible to relight a shot in any compositing package that can import the file format.

Outputting the layers – or any one of the other 21 Arbitrary Output Variables – alongside a regular unbiased render does not increase total calculation time, making it effectively free to generate extra passes.

A new object-based region render option offers a similar workflow when it comes to materials changes.
