AR Flame Lens
Overview
An interactive AR lens for Snapchat featuring a 3D flame character inspired by Calcifer. The character reacts to hand gestures in real-time — growing or shrinking depending on whether the user's hand is open or closed. The lens combines 3D animation, gesture tracking, particle effects, and a stylized 2D background to create a playful, animated companion experience.
Challenge
How can we bring character and emotion into a simple AR interaction using limited input (like hand gestures), while keeping performance optimized for mobile?
Solution
The final AR lens allows users to summon a floating flame character that feels alive and reactive. The character scales up and “flares” when users open their hand, and shrinks or calms down when the hand closes. The soft particle glow and whimsical background create a cozy, magical atmosphere.
Tools & Technology
Software: Snap Lens Studio, Blender (modeling/animation), Photoshop (2D background), After Effects (particles).
