RandomControl previews relighting in Arion 2.4

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.
