水下场景有着独特的光学特性,需要专门的渲染设置才能呈现令人信服的效果。本教程以蛇颈龙水下巡游为例,详解Blender Cycles的水下渲染方案。水体体积是核心:使用Principled Volume节点设置Absorption Color为蓝绿色调,Density根据水的浑浊度调整,Anisotropy值0.3-0.6模拟水中悬浮粒子的前向散射。God Rays通过Volume Scatter配合强方向光实现,Light Path节点的Is Shadow Ray输出控制光线穿透深度。焦散效果使用Caustics选项开启,配合Mesh Light或Emission材质在水底投射光斑图案。水下雾效的距离衰减比空气中更快,通过Fog Density控制可视距离,远处物体逐渐融入水体颜色。气泡系统使用Particle System从恐龙嘴部和鳍部发射,大小和上升速度随深度变化。水面从水下观看呈现镜面反射效果,使用Glass BSDF配合IOR 1.33模拟水-空气界面。色彩校正方面,水下场景整体偏蓝绿,红色波长被优先吸收,需要在Compositing中补偿白平衡。后期添加色差和镜头水滴效果进一步增强水下沉浸感。
