About the Team — Complex Interactive

Kodai

LEAD DEVELOPER // COMPLEX INTERACTIVE

Unity Experience8+ YearsPrimary DisciplineComplex SystemsVRChat FocusAI / NPC Engineering

Kodai is the lead developer of Complex Interactive, responsible for the complex scripting, programming, and technical systems used throughout its worlds. He also contributes systems work to Sable’s Backrooms VRC Series.

With more than eight years of Unity experience and several years working in C#, Python, and UdonSharp, Kodai specializes in translating ambitious game concepts into functional VRChat systems. His work includes artificial intelligence, NPC behavior, state-driven gameplay, multiplayer interactions, player statistics, survival mechanics, inventories, objectives, debugging, and performance optimization.

Kodai’s strongest specialty is highly complex AI and NPC development inside VRChat. He builds these as complete gameplay frameworks—combining perception, decision states, pursuit, combat, synchronization, environmental responses, and reliable recovery behavior—rather than isolated scripted effects.

Sable

BLENDER MODELER // ENVIRONMENT ARTIST

Primary DisciplineBlender ModelingEnvironment FocusImmersive BackroomsAdditional WorkAvatars / Entities / Audio

Sable is a close friend and creative collaborator of Kodai’s, recognized within Complex Interactive for exceptional Blender modeling and deeply immersive environmental work.

His attention to detail is especially visible in his Backrooms environments, where architecture, scale, materials, lighting, decay, and environmental storytelling work together to create spaces that feel convincing and unsettling. Rather than treating a level as a simple collection of rooms, Sable builds environments with a strong sense of place and atmosphere.

Beyond environment modeling, Sable has extensive experience creating original avatars, entity designs, custom assets, and sound effects. This combination allows his visual and audio work to support the same creative direction, giving projects a more cohesive identity.

Wiser

STORY DIRECTOR // CONCEPT DEVELOPMENT

Primary DisciplineStorytellingCurrent ProjectDreamcoreTeam PositionKodai's Right-Hand

Wiser is Complex Interactive's story and concept specialist, helping transform early ideas into coherent worlds, characters, themes, and visual directions. He develops narrative concepts, gathers and evaluates concept art, and helps determine how a project's atmosphere and story should be communicated through the environment.

As Lead Director of his upcoming Dreamcore world, currently in planning, Wiser is defining its creative identity from the ground up. His work includes narrative structure, surreal world concepts, emotional tone, environmental story beats, visual references, and the connective ideas that make separate locations feel like parts of one deliberate experience.

Wiser also contributed to Nullosis, supporting Kodai with story development, creative feedback, concept exploration, and ideas that strengthen the relationship between its characters, lore, and gameplay. His perspective helps the team test whether an idea is merely interesting or truly supports the larger world.

As Kodai's trusted right-hand collaborator, Wiser acts as both a creative sounding board and a narrative counterbalance to the technical side of development. Kodai builds the systems that make a world function; Wiser helps ensure those systems serve a memorable story, a distinct atmosphere, and a clear creative purpose.
