植被交互是让恐龙融入环境而非浮于表面的关键。本教程讲解UE5中植被交互的实现方案。Interactive Foliage系统是最直接的方案:在Foliage Type中启用Touch Reaction,设置Response Scale和Damping控制植被被恐龙推开后的弯曲幅度和回弹速度。大型恐龙经过时树木摇晃、灌木压弯、草丛分开;小型恐龙仅影响低矮植被。Physics Field组件提供更精细的控制:在恐龙碰撞体周围创建径向力场,影响范围内的Foliage Instance根据距离和方向计算变形量。这种方式支持任意方向的推挤而非仅限于垂直下压。植被恢复动画通过Spring Damping参数控制,不同植物有不同的弹性系数:草本快速回弹,木本缓慢恢复。落叶和断枝从受力点脱落,使用Niagara Spawn on Collision触发。脚印中的植被压痕通过RVT持久化,与地形破坏系统联动。性能方面,Interactive Foliage的影响半径应限制在摄像机附近,远处的植被使用Wind Only模式。GPU Compute Shader加速大规模植被的物理更新。
