Henrik Dahlberg
AI and rendering engineering in immersive technology for film, music, and live entertainment.
About
Henrik is an engineer and consultant in AI and computer graphics for film production, live entertainment and immersive experiences. His work spans the full lifecycle of production systems, from research and prototyping through implementation, hardware and software integration, testing, client coordination, deployment, and on-set operations.
Contributor to two Academy Sci-Tech Award-winning projects: Disney's ML Denoiser (2025) and ILM's Lama shading system (2026), both now used industry-wide via Pixar's RenderMan. As engineering lead for the ML Denoiser initiative, he owned scoping, evaluation, and pipeline integration of the AI denoiser that has been used on over 100 films since 2018, including every Pixar film since Toy Story 4. His work on Lama included developing the layerable shaders used for all character and costume rendering on ABBA Voyage, as well as procedural noise systems, dispersion rendering, and hair shading shipped on Star Wars: The Rise of Skywalker, No Time To Die, and Marvel's The Eternals, and now used across all ILM productions and the wider film industry via RenderMan.

Henrik built and deployed real-time AI face swap and voice translation systems across film, broadcast, and live events. He developed the neural voice translation pipeline and face swap suite for Eminem's 2023-2024 campaign including the Houdini music video and the 2024 VMAs live performance, served as live operator across 80+ arena shows on Drake's North American tour, built the first live AI voice translation for Cai Guo-Qiang's TED Talk, and delivered voice cloning and holographic face swap technology for the COP28 opening ceremony in Dubai.
Earlier work includes real-time rendering for ILM's StageCraft virtual production system at Pinewood Studios, shipping features for The Mandalorian and Obi-Wan Kenobi, and real-time path tracing at Unity Technologies. Henrik holds an M.Sc. in Applied and Computational Mathematics from Aalto University and KTH Royal Institute of Technology, with specialisations in Mathematical Statistics and Light Transport Simulation.

Selected Work
Eminem
AI Engineer ยท Metaphysic ยท 2023-2024

AI voice and face work across Eminem's 2023-2024 campaign. Built the neural voice translation pipeline and real-time face swap suite for Houdini, PR campaigns with Complex, and the 2024 VMAs live performance.
ABBA Voyage
Rendering Engineer ยท Industrial Light & Magic ยท 2022

ILM digitally recreated the four members of ABBA as photoreal digital humans for the Voyage concert. Four continuous performances were synthesised from the original band members and stand-in actors. I worked on rendering technology and on-set support, and developed the layerable shaders used for all character and costume rendering on the project.
Drake: It's All A Blur Tour
AI Engineer ยท 2023-2024

Live generative AI visuals for Drake's North American arena tour. I served as machine learning engineer and live operator across 80+ shows across North America. Responsible for face swap data curation, model training and deployment, on-site machine setup, system maintenance, client interaction, and real-time operation during each performance.
Star Wars: The Rise of Skywalker
Rendering Engineer ยท Industrial Light & Magic ยท 2019

Rendering technology and procedural terrain generation using Phasor Noise, a procedural noise function implemented as part of the Lama framework.
The Mandalorian
Real-Time Rendering Engineer ยท Industrial Light & Magic ยท 2023

StageCraft virtual production rendering via the Helios real-time engine for the Disney+ series. On-set technology operations at ILM's LED volume stage.
Obi-Wan Kenobi
Real-Time Rendering Engineer ยท Industrial Light & Magic ยท 2022

Developer on Helios, ILM's real-time render engine (Vulkan Ray Tracing) for the StageCraft LED volume. Shipped ray-traced refraction, parallel texture compression, and existence mipmapping with alpha distribution.
Aladdin
Rendering Engineer ยท Industrial Light & Magic ยท 2019

First film with full Lama shading deployment and first ILM production to use the ML denoiser on photorealistic live-action content. I worked on rendering technology and lighting for the CG Genie character and environments.
UNFCCC COP28: Sheikh Zayed Hologram

Voice cloning and live face swap pipeline recreating the late Sheikh Zayed bin Sultan Al Nahyan as a hologram for the COP28 opening in Dubai, UAE. The holographic Sheikh Zayed walked on stage and delivered a speech in Arabic to assembled world leaders.
Cai Guo-Qiang: TED2024
AI Engineer ยท Metaphysic ยท April 2024

I built and deployed the real-time Mandarin-to-English voice translation pipeline for artist Cai Guo-Qiang's TED Talk. A custom voice model reproduced Cai's own voice in English, preserving his tonality, timbre, and cadence. The translated speech was output through the PA system as he spoke on stage. A first in TED history.
