高质量的UV展开是优秀贴图的基础。本教程总结恐龙模型UV展开的最佳实践经验。首先是UV岛划分策略:按照材质区域和功能区域分割UV岛,头部、躯干、四肢各自独立,便于分区绘制和后期修改。接缝位置应选择在视觉不敏感区域,如身体中线、四肢内侧和下巴下方。对于对称模型,可以重叠对称部分的UV以节省空间,但要确保接缝处的连续性。UV空间利用率目标在75%-85%之间,过大浪费贴图分辨率,过小导致像素不足。使用Pack Islands工具自动排列后,手动调整重要区域(如面部)的UV比例给予更多空间。UDIM工作流适合超高分辨率需求,将不同身体部位分配到不同的UV象限。检查UV质量时要关注拉伸度(Stretch)、重叠检测和边界对齐。在Substance Painter中绘制前,先烘焙Curvature和Occlusion贴图验证UV是否正确。常见问题包括镜像UV导致的对称纹理、扭曲UV造成的拉伸纹理和过密UV引起的锯齿。养成规范命名和整理UV集的习惯,为团队协作和后续迭代奠定基础。
