After trimming the UVs of Bot1, I discovered that despite using an advanced relaxation algorithm, the texture still exhibited significant stretching, leading to a serious waste of texture pixel utilization. Therefore, when unwrapping the UVs for Bot2, I explored new methods. However, tools like ZenUV, UniV, and Packmaster3 in Blender failed to meet my expectations. Eventually, I learned about industry-standard UV mapping practices through tutorials and turned to specialized software, RizomUV. During the process, I straightened all UV islands wherever possible and leveraged RizomUV’s multi-quadrant auto-packing feature. This improved the UV map utilization from 75% to 81% while avoiding potential UV seams during the baking process.
