沙尘暴是干旱环境中恐龙面临的极端天气事件。本教程讲解Blender中沙尘暴效果的实现。沙尘主体使用Volume Scatter配合高密度的Noise Texture,Scale控制沙团的粗细,Anisotropy设为正值使光线沿风向散射。沙尘的颜色使用Warm White偏黄褐的Volume Absorption模拟悬浮颗粒的光吸收。风速方向通过Mapping节点的Rotation统一控制,Animated Texture Coordinate实现沙尘的整体移动。能见度随沙尘密度急剧下降,使用Mist Pass控制远景的消隐距离。前景恐龙在沙尘暴中的表现:眯眼(Blend Shape控制眼睑闭合度)、低头避风(头部下倾角度与风力关联)、步伐不稳(身体侧倾和脚步踉跄)。沙粒打击皮肤的效果通过微小的Bump Animation模拟。地面扬沙使用Particle System从脚部落地点向上喷射,受Wind Force Field吹向顺风方向。光源在沙尘中被严重散射,直射光变为弥漫的均匀照明,阴影几乎消失。后期添加Film Grain和Chromatic Aberration模拟沙尘对镜头的影响。渲染时使用Branched Path Tracing加速体积采样的收敛。
