Expand 3D model

unwrap the UVs of the 3D model shown in the image.
About one-third of the image should be a reference view displaying the 3D model itself.The remaining area should include the UV layout for the head, body, and limbs.Unwrap the surface of the 3D model and flatten it into a single 0–1 two-dimensional UV space.

展开图中所示 3D 模型的 UV 贴图。
图像中约三分之一应为参考视图，显示 3D 模型本身。剩余区域应包含头部、身体和四肢的 UV 布局。展开 3D 模型的表面，并将其展平为单个 0-1 二维 UV 空间。
