# Unity 2D Tooling This skill covers the non-physics half of Unity's 2D toolset: sprite import and slicing, Sprite Atlas packing (including V2 format and platform variants), 9-slice sprites, sprite sorting (Sorting Layers, Sorting Group, Sprite Mask), the full Tilemap/Tile Palette authoring pipeline, Tilemap collision components, 2D lighting in URP, and the 2D Animation (Sprite Skin/bone rigging) package. 2D physics bodies, colliders, joints, and effectors are owned by the sibling `unity-physics` skill — do not duplicate that material here; this skill only touches collision components (TilemapCollider2D, sprite auto-collider generation) as they relate to authoring, not physics simulation behavior. ## Retrieval Sources All paths below were re-verified present on disk under `/media/artiq/FRESH_DRIVE/Books/Unity6/Documentation/en/` as of this pass (Unity 6.3 LTS / 6000.3 docs, built 2026-08-10). Paths are relative to that root. | Source | Path | Use for | |--------|------|---------| | Sprite import & Texture Type | `Manual/sprite/import-images-sprites/import-images-sprites-landing.html`, `Manual/texture-type-sprite.html` | Texture Type = Sprite, Sprite Mode (Single/Multiple), pixels-per-unit, pivot, mesh type | | Sprite Editor window | `Manual/sprite/sprite-editor/sprite-editor-window-reference-landing.html`, `Manual/sprite/sprite-editor/sprite-editor-window-reference.html`, `Manual/sprite/sprite-editor/use-editor.html` | Slicing spritesheets into sub-sprites, editor workflo
