If you’re new to 3D modeling, good UV mapping is critical to getting a good result for game output. With more complex scenes, you can end up with a lot of wasted space between the polygons in your UV map.
One of the most tedious parts of doing a good 3D model for game use is making a good UV map that doesn’t waste all that space. Producing a high-quality, efficient, UV map for a detailed model can take hours or days of work, depending on the complexity.
