GPU2DAnimator

GPU2DAnimator — GPU-Driven 2D Skeletal Animation (VAT) for URP

A professional-grade 2D animation acceleration solution for Unity.

By baking SpriteSkin motion into EXR textures and sampling in the GPU vertex stage, it removes Animator/SpriteSkin CPU cost, enabling massive batching and stable FPS on mobile, PC, and consoles. 

One-click bake, drop-in prefabs, and lightweight runtime—no runtime rigging or Animator graphs.

Use Cases

------------------------

2D characters, crowds, and NPC swarms

Action/platformers with many on-screen actors

UI/live avatars and 2D VFX sequences

Mobile titles needing stable frame time

Projects targeting URP with SpriteRenderer + SpriteSkin

Core Features

------------------------

One-click Baker: Pre-bake per-clip motion JSON → VAT textures → merged mesh/prefab

Runtime Component: Per-clip play/loop, default clip fallback, time scale, child-apply

Instancing-friendly: Minimal per-instance data; _FrameIndex drives animation

Smart Assets: Linear EXR, uncompressed, point, clamp (auto import settings)

Clean Config: JSON-based clip ranges/fps/duration; 

inspector clip controls and preview

Production Shader: IGD/GPU2DAnimationShader 

Cross-Platform Optimization

Consistent performance on mobile, PC, and consoles

Stable FPS with large crowds and many animated actors

Low CPU usage, reduced spikes from Animator/SpriteSkin

You’ll Benefit

-------------------------

Significant CPU offload and fewer bottlenecks

Smooth playback with large numbers of animated sprites

Minutes-to-integrate pipeline, production-ready prefabs and materials
