When starting to unwrap a 3D model’s UV map as a beginner, use simple geometry first, run your software’s automatic tool (e.g., Blender’s Smart UV Project) for a base layout, add seams along less visible edges (like under arms or inside creases) to minimize distortion, then organize the flattened UV “islands” so they don’t overlap and scale evenly.
Practice with basic shapes (cubes, cylinders)—they’re straightforward for learning seam placement, and built-in software guides make it less frustrating as you get comfortable.
