  SPRAY META QUEST SPRAY CAN UI ADJUSTMENT

Inspiration

SPRAY started as a small idea triggered by a single LinkedIn post — someone showed a cool stylized VR spray effect, and it sparked a thought: “I can build that. And it would be perfect for my Streets of Miami/New York projects.”

That spark turned into a sprint.

For two straight weeks — from morning until early morning — the project evolved from an effect into something bigger: a creative tool, a chill hangout space, and a canvas for self-expression. The nostalgia of tagging walls in games like The Warriors, the culture of graffiti, and the raw energy of urban art all played into shaping SPRAY’s identity.

The mission became clear: Give people freedom to create — fast, fluid, and without barriers.

What it does

SPRAY is a VR graffiti sandbox experience where players can paint freely in immersive urban environments using intuitive spray mechanics. Multiple nozzle types and spray patterns A large color palette and swappable cans Multiple canvas types (walls, billboards, whiteboards, etc.) Adjustable spray settings (pressure, flow, drips, softness) Players can experiment casually, paint serious art pieces, collaborate online, or simply unwind and express ideas in a stylized urban setting. A free version exists to ensure creativity is accessible to everyone.

How we built it

SPRAY was built in Unity using: Custom shader-based spray rendering Dynamic brush and drip simulation Meta XR SDKs for VR interaction Netcode foundations for future shared painting modes Texture streaming and compression balancing for real-time painting performance Fine control over responsiveness, layering, and blending makes the spray feel tangible and satisfying — not just a decal.

Challenges we ran into

Achieving realistic spray scatter, glow, and transparency without destroying performance Choosing texture compression formats that kept art sharp but memory-friendly Aligning real-time rendering with VR feel — making spray look soft but act precisely Balancing hand tracking simplicity with precision, stability, and workflow

Networking prototypes also required iteration to sync painter positions, strokes, and texture updates efficiently.

Accomplishments we’re proud of Realistic, tunable spray mechanics built from scratch A clean UI panel where every setting updates live in real time Fast iteration and completion of a working prototype in roughly two intense weeks Early testers immediately compared it to King Spray — which validated the quality

What we learned Two big lessons: Backup constantly. When building systems that are visual, layered, and experimental, one tiny break can cost hours. Iteration beats perfection. Polish came from tuning, testing, refining — not guessing.

What’s next for SPRAY SPRAY is expanding into: Online collaborative painting Turf-war competitive modes Passthrough MR so players can paint onto surfaces in their real environment Themed urban environments tied into Streets of Miami and Streets of New York Achievements, unlocks, and community challenges Long term, SPRAY aspires to become the creative hub for VR graffiti culture — part tool, part game, part social canvas.
