羽毛卡片是游戏和实时应用中表现恐龙羽毛的主流方案。本教程详解Blender中羽毛卡片系统的完整制作流程。首先在ZBrush或Blender中雕刻几片高精度羽毛作为模板,提取其轮廓和纹理信息。然后创建平面几何体作为卡片基底,应用羽毛的透明度贴图定义外形。UV布局采用Atlas方式将多种羽毛变体打包到同一张贴图中,减少Draw Call。卡片的排列使用Geometry Nodes实现程序化分布:沿皮肤表面法线方向插植,密度和大小通过Weight Paint控制区域变化。每张卡片添加轻微的随机旋转和弯曲,避免整齐排列的人工感。排序问题通过Alpha Hashed或Dithered Transparency解决,配合Backface Culling减少渲染负担。LOD策略分三级:近景使用双层交叉卡片增加体积感,中景单层卡片,远景退化为法线贴图。动画方面,使用Shape Key或Vertex Group驱动卡片根部的摆动,配合Wind Force Field模拟风吹效果。材质使用Principled BSDF的Transmission和Sheen参数模拟羽毛的各向异性光泽。最终在EEVEE中测试渲染效果,确保透明排序和阴影投射的正确性。
