Overview

Crowd Cheer is a GPU-driven crowd shader that renders hundreds of animated spectators on simple flat meshes — no GameObjects per character, no Animators, no skinned meshes. Just a texture atlas and a Quad.

Perfect for stadiums, concerts, arenas, sports games, and any scene where you need a lively crowd without killing performance on mobile and VR.

How it works:
A sprite atlas with character variants (columns) and animation frames (rows) is tiled across a flat mesh. The shader automatically randomizes appearance, animation phase, and orientation per tile — every character looks unique with zero CPU overhead.

Key Features:

• 100% GPU — no scripts required, no per-character GameObjects
• Sprite atlas animation — up to 16 character variants x 8 animation frames
• La Ola / Mexican Wave — configurable stadium wave with direction, speed, width, and pose controls
• Crowd density — dynamically control how full the stadium is (0–100%)
• Distance fade — automatic LOD, clips distant characters to save fillrate
• Random flip X — doubles visual variety at zero cost
• Color tint + per-character variation — team colors, lighting moods, natural diversity
• UV tiling & offset — control how many characters appear per mesh
• World-space randomization — duplicate meshes automatically look different
• URP lighting — responds to ambient SH + main directional light
• VR-ready — full Single Pass Instanced stereo support
• GPU Instancing — supported out of the box
• Alpha cutout — ZWrite On, no transparency sorting issues
