DIVA-DAG (Digital Art Studio Roppongi), a CG production company located in the heart of Tokyo, uses Reality Engine, the real-time compositing platform developed by Zero Density, to exponentially increase creativity in its studio.

he studio features two separate spaces, one for motion capture and the other for virtual production wih a green screen studio. While searching for the right technology, the team discovered Reality Engine, the cutting-edge real-time compositing platform.

DAG team was impressed by its customization, integration with camera tracking, and keying capabilities. They ultimately chose Reality ecosystem because it possessed all the tools that would allow them to create special worlds. Zero Density’s regional partner Reinphase has carried out the installation and training for the studio.

“The greatest appeal of Reality Engine is being able to check the completed image in real-time. And it’s possible to shoot videos for different production materials, even with a relatively simple setup.” said Horita Hiroki, Section Manager at DAG. “The colors of the floor and wall in our studio are slightly different, but this is not a problem for Reality Keyer. The color variation can be compensated very easily. Complex configurations were never necessary.”


Work process

DIVA Studios follows a streamlined process when working with clients. They first consult with the client and create a design sketch, which the client then approves. Meanwhile, the client chooses a virtual set from Unreal Engine Marketplace, which DIVA customizes using Reality and performs a test shoot. This entire process, from initial consultation to shooting, typically takes only a week, significantly reducing the time required compared to using alternative game engines, which they used previously.

Nihommatsu Katsumi, Chief Operating Officer at DAG, said, “What struck me at the first demo was that the studio setup was very basic. Just a green sheet in a section of the office. Also, the lighting equipment was minimal, but the green was completely rendered, even in detailed sections such as the hair. The setup didn’t seem complex at all, but the green was completely rendered. This means that the potential would be even greater with a high-tech studio.”

DIVA Studios has primarily been shooting music videos and dream-like sequences for TV programs. Artists would sing or dance in the green background space, and the team would create and add background graphics or customize resources already available on Unreal Engine Marketplace. The team has also shot sequences by combining a virtual background with props from an actual background image.
Real-Time Visual Magic

Nihommatsu Katsumi, Chief Operating Officer at DAG, said, “People may have experience with CG compositing in postproduction, or some may have seen it in film-making, but most people have never seen real-time compositing with such detailed and high-quality keying, so they’re always impressed.”
