皮肤褶皱是恐龙模型生动感的关键细节。本教程讲解ZBrush中褶皱雕刻的系统方法。褶皱的形成遵循物理规律:压缩产生堆积褶皱,拉伸产生张力纹路,重力产生下垂褶痕。关节内侧(肘窝、膝弯、腋下)是褶皱最密集的区域,使用Dam Standard刻画主褶线,Smooth柔化两侧过渡。颈部在转头时产生螺旋形褶皱,低头时产生横向堆叠褶。腹部的褶皱受重力和呼吸双重影响,站立时下垂形成纵向褶,俯卧时展开变平。褶皱的深度和锐度与皮肤厚度相关:厚皮恐龙(如甲龙)褶皱宽而浅,薄皮恐龙(如翼龙)褶皱窄而深。动态褶皱需要在多个姿态下验证:同一个褶皱在伸展时消失、压缩时加深,这种状态变化增加了模型的真实感。使用ZBrush的Pose功能预设几个关键动作来检验褶皱的动态表现。导出时褶皱信息同时保存在Displacement和Normal贴图中,前者用于近距离渲染的真实几何变形,后者用于中远距离的快速渲染补偿。
