ARRI has officially released LUKA, a new Unreal Engine plugin designed to bridge the gap between virtual and physical filmmaking. Announced on June 24, 2026, the tool drops accurate digital replicas of ARRI's lighting fixtures and cinema cameras into a real-time Lumen environment, giving content creators a powerful new asset for previsualization and on-set virtual production.

According to the announcement, LUKA is built to support the full production workflow, from previs to LED wall stages and post-production handover. The inclusion of DMX and LiveLink control within the plugin means creators can link virtual lights and cameras directly to real-world lighting desks and tracking systems, making the transition from previs to physical shoot more seamless than ever before.

For content creators working in real-time engine-based production, the ability to simulate specific ARRI fixtures with accurate photometric behavior inside Unreal Engine is a notable step forward. The real-time Lumen integration allows for dynamic global illumination and reflection previews that match the look of the intended lighting setups, saving time and guesswork during the planning phase.

ARRI is currently offering LUKA as a free three-month trial license for commercial use. This trial period gives creators and studios the opportunity to test the plugin within their existing Unreal Engine pipelines without upfront cost, lowering the barrier to entry for high-end virtual production tools. While full pricing and licensing details beyond the trial remain unannounced, the release signals ARRI's continued investment in virtual production solutions tailored for cinematographers, VAD artists, and technical directors.
