能够实现GPU实例化渲染,ue提供了两个组件,InstancedStaticMesh(实例化静态网格体组件)和HierarchicalInstancedStaticMesh (层级实例化静态网格体组件),这两种的区别是,实例化静态网格体组件,只能渲染一种,层级实例化的意思可以实现lod分级渲染。 实例化组件只能使用静态网格体,不能够使用骨骼网格体,我这里使用的是之前买...
需要承认的是,尽管 Unreal Engine 5 非常强大,但并非无所不能,想要搭建出像上面那样能够满足游戏项目性能要求的自然场景,我们还将会面临许多除引擎技术之外的挑战. 在开放的自然场景中,植被产生性能问题的频率以及所造成的影响往往不亚于光影和特效。 在UE5中,如果谈到植被优化,大家的第一反应想到的可能是减面,实例...

I have InstancedStaticMesh, and i want to change color of only one instance. To do this i use SetCustomDataValue node in my BP to pass float value to material instance. But when i call node, nothing happens in game; however if i eject by pressing F8 and select instance, it changes...

权衡一下,你可以在多个StaticMeshComponent中复用生成的UStaticMesh(获得Instanced Rendering带来的好处),而如果你想要具有多个"相同"的PMC,则需要将Mesh复制到每个PMC中。此外,你还可以使用 SMC 获得额外的渲染功能。例如,PMC中使用的FProcMeshVertex仅支持4个UV通道,但UStaticMesh最多支持7个UV通道。UStaticMesh还...
