New E.D. Films Short ‘Three Trees’ Done All in Unreal

Built entirely within Unreal Engine, the film is written and directed by M.R. Horhager, illustrated by Aaron Hong, and narrated by Whoopi Goldberg. 

E.D. Films has announced its latest project, Three Trees, a short film built entirely within Unreal Engine. Utilizing the aesthetics of a children’s book and starring the vocal talents of EGOT winner Whoopi Goldberg, the short will premiere June 24 at the Palm Springs International ShortFest.

Written by Emmy-nominated television and film director M.R. Horhager and illustrated by veteran art director Aaron Hong, Three Trees is the story of three friends who each happen to be a distinct species of tree. As they grow and change over the course of a year, each of the trees experiences the new seasons in their own unique way, which initially sets them apart. With the help of their friends, the trio come to embrace the differences that make them who they are. 

To deliver their message of acceptance, Horhager and Hong envisioned a short film with a children’s book aesthetic, featuring a forest filled with multi-colored, geometric trees. But to bring it to life, they wanted to utilize filmmaking techniques that have traditionally been the province of live-action projects, including elements like final framing and cinematography. To have that freedom to experiment, the duo needed to explore the digital environment from any angle, in real-time. This meant using a game engine, leading the duo to E.D. Films, experts in adapting distinct animation properties and one of the first animation studios in the world to have received an Epic MegaGrant.

“We’ve been working with game engines for over a decade now, but recently Epic has made some incredible additions to Unreal Engine that have allowed us to streamline how we approach many of our animation projects,” said Emily Paige, co-founder and lead producer for E.D. Films. “Having access to Epic’s support team and the community of filmmakers working with Unreal has been incredible. With their help, our work on Three Trees really showed off what real-time animation production is capable of.”

E.D. Films began by adapting Hong’s 2D illustrations into a vibrant 3D environment. Using Unreal’s procedural tools, including the internal foliage and terrain options, artists were able to quickly create a complete forest that helped capture the unique storybook-inspired feel. Material creation and instancing systems were then employed to build textures and surfaces like tree bark and undergrowth, along with the distinctive leaves of each tree. The team was then able to leverage Unreal’s season-switching system to transition the forest from fully green in the summer to the colors of autumn, then to a layer of winter snow before showing flowers bloom under spring conditions.

With the stage set, Horhager and Hong were able to jump into the scene and move through it in real-time. With traditional animation, every moment needs to be intricately planned and determined in advance, but with Unreal Engine, E.D. Films gave the directors the freedom to take control of the camera. From there, the duo was able to experiment and determine the best angles, movement, and positioning for each shot. Once the short film’s look was established, it was then rendered within the game engine, ready for Goldberg’s narration.

Following the completion of the Three Trees short film, Horhager and Hong looked to adapt the assets and completed materials to bring the story to additional platforms, starting with a traditional children’s book. The duo and E.D. Films are in discussion for future releases, including a planetarium dome output.

Three Trees marks the latest step in E.D. Films’ ongoing experimentation with using game engines to produce professional-quality animation. Since 2014, it has been one of the leaders in creating new pipelines and original tools within Unreal Engine, including the industry-first PSD to 3D conversion system that has helped turn a generation of 2D artists into 3D filmmakers. The studio is coming off the release of its own short film, Return to Hairy Hill, which took advantage of Unreal Engine’s previs and real-time rendering tools, along with several of E.D. Films’ proprietary tools. The film recently won the prestigious Guy L. Coté grand prize for Best Canadian Animated Film at Les Sommets du Cinéma d’Animation 2023.
