大型恐龙的物理碰撞是性能敏感点。本教程讲解UE5中恐龙碰撞优化的系统方法。碰撞体简化是第一原则:永远不要用渲染网格做碰撞,使用简化的Convex Hull或Capsule组合代替。霸王龙的碰撞体可以用3-4个Capsule近似:躯干一个大的水平Capsule,头部一个倾斜Capsule,尾巴一串串联的小Capsule。Physics Asset Editor中可视化编辑和调整碰撞体。碰撞通道(Collision Channel)合理分类:恐龙本体使用Pawn通道,可破坏物体使用Destructible通道,触发器使用OverlapOnly通道。避免不必要的碰撞对:通过Collision Presets排除不需要互相检测的对象组合。Continuous Collision Detection(CCD)仅在高速运动的恐龙上启用,静止或慢速的使用Discrete检测即可。物理子步数(Substep)根据精度需求调整,一般恐龙4-6步足够。Sleep Threshold让不活跃的刚体进入休眠释放计算资源。对于群体场景,考虑使用Simplified Physics LOD:近距离完整物理,中距离简化碰撞体,远距离完全禁用物理改用Kinematic动画。Profiling使用Chaos Visual Debugger识别碰撞热点。
