雪地足迹是冬季恐龙场景的重要叙事元素。本教程演示Blender中实现雪地足迹的两种方案。方案一使用Dynamic Paint:将雪面设为Canvas,恐龙脚部设为Brush,Paint Type选Displace。Brush的Radius和Strength控制足迹的大小和深度,Dissolve Time控制足迹的回填速度。雪面的Displace modifier接收Dynamic Paint的输出作为置换量。优点是实时交互、支持任意路径,缺点是分辨率受限于Canvas网格密度。方案二使用Geometry Nodes:在地面网格上检测恐龙脚部的距离场,根据距离计算凹陷深度,通过Set Position节点下移顶点。这种方法更灵活,可以添加足迹边缘的雪堆隆起、底部的压实纹理和侧壁的松散颗粒。雪的材质使用Principled BSDF配合SSS模拟光线穿透积雪的效果,Roughness接近1.0表现干燥粉雪的哑光质感。足迹内部的雪更密实,Roughness略低且有冰晶光泽。粒子系统从脚步抬起时发射飞散的雪花,增加动态感。两种方案可以结合使用:Geometry Nodes处理静态足迹,Dynamic Paint处理实时交互。
