What is UV Unwrapping?

UV unwrapping is the process of projecting a 3D model's surface onto a 2D plane so that textures can be accurately applied. In Blender, UV unwrapping is an essential step for texturing, baking, and many forms of analysis. Each point on the 3D surface is mapped to a coordinate (U, V) in 2D space, allowing images to wrap seamlessly around complex geometry.

How to UV Unwrap in Blender

1. Select the mesh you want to unwrap.
2. Mark seams where you want the mesh to be "cut" for flattening.
3. In Edit Mode, press U and choose an unwrapping method (e.g., Unwrap, Smart UV Project).
4. Use the UV Editor to adjust the layout for minimal stretching and optimal texture placement.
5. Export or bake textures as needed.

UV unwrapping is not just for texturing; it's a foundational skill for any 3D workflow involving analysis, baking, or data visualization.
