In Unity, sprites are 2D graphic assets used in 3D scenes to add UI, characters, or effects alongside 3D models.
- They’re 2D textures mapped to simple quad meshes: This makes them lightweight for rendering 2D content in 3D environments—ideal for 2D games or mixed 2D/3D projects.
- How to use sprites in 3D: Import a PNG/JPG file, set its “Texture Type” to Sprite in the Inspector, then drag it to the Hierarchy to place as a 2D object in your 3D world.
