Video: Geomerics’ new Enlighten 3 lighting system

Wednesday, March 4th, 2015 | Posted by Jim Thacker

Geomerics’ new Subway demo shows off the dynamic lighting capabilities of Enlighten 3, including the option to destroy terrain and keep indirect lighting consistent. You can read a making-of on the company’s blog.

Geomerics has announced Enlighten 3, the latest update to its lighting middleware – recently in the news thanks to Unity 5, where it provides the engine’s new real-time global illumination system.

Including both artist tools and a runtime component, Enlighten enables a range of approaches to in-game lighting, from fully baking lighting data all the way up to dynamic GI.

The technology is used by a range of other well-known game engines, including EA DICE’s Frostbite family, and is available fully integrated into Unreal Engine 3 and 4 – the demo above uses UE4.

The main new feature in Enlighten 3 is its new Forge editor (shown in the video above), intended as an artist-friendly environment for lighting and shading, with support for physically based shaders.

The viewport integrates Silicon Studio’s Yebis middleware – also used in the viewport of Allegorithic’s Substance product range – to provide a near-final-quality view of game assets.

Forge offers built-in import functionality from 3ds Max and Maya – the video shows it linking live to Maya – and can be integrated with studios’ proprietary scene layout tools.

Geomerics also tells us that it has also worked on its shader code to enable in-game assets to make better use of Enlighten lighting data. Indirect lighting now makes use of the albedo of a surface, baked lightmaps include a final gather pass, and directional output can be colour-separated according to RGB channel.

Pricing and availability
Enlighten 3 will be available at the end of March. Being middleware, it’s priced on demand, typically on a per-title or royalty-share basis.
