One Click Atlas Creator

# Material Atlas Creator — High-Performance Atlas Baker & Mesh Remapper

One-click atlas baker that merges textures and materials into one for massive draw-call reduction across all Unity render pipelines.

Material Atlas Creator is a fast, reliable Unity Editor tool that automates texture atlas generation and mesh UV remapping so your scenes render with far fewer draw calls. Designed for creators who want immediate performance wins — mobile games, VR, large open-world scenes, or packed product demos — it converts multi-material objects into single-material objects backed by a single atlas PNG and remapped meshes.

Note: objects with skinned mesh renderer and tiled materiel cannot be created as an atlas, in future updated we will upgrade these features.

## Key Features

- **Single Material Conversion:** Combines all materials into one optimized atlas material.

- **High-Resolution Atlas Support:** Up to 16K (16384x16384) atlas textures.

- **Advanced Texture Packing:** Smart retry logic and padding for efficient packing.

- **Automatic Shader Detection:** Works across Built-in, URP, HDRP.

- **Skinned Mesh Support:** Bakes and restores skinned meshes safely.

- **Undo & Restore System:** Non-destructive workflow with one-click revert.

- **Optimized Readable Copies:** Maintains texture quality and transparency.

- **Mesh UV Remapping:** Automatically adjusts UVs for atlas regions.

- **Real-time Stats:** Shows packing efficiency and draw-call reduction.
