HISM耗时的一个原因就在这里,即FClusterTree的裁剪。首先会有一个buildtree的过程。 进一步会在FHierarchicalStaticMeshSceneProxy::GetDynamicMeshElements(..)方法内调用traverse方法裁剪构建好的树。这里是构建好之后的查询耗时。 在traverse方法内,首先会查看当前node是否会被裁剪掉,如果是的话,那么其所有的子节点则...
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...

因此,我们推荐让一组instanced mesh保持在一个小区域,例如a pile of stone, trash tags或者stack of box以及distant modular building。 Hierarchical Instanced Static Meshes 如果一组static meshes需要使用LOD,可以考虑Hierarchical Instanced Mesh。 像标准instanced mesh一样,hierarchical instance不但会减少它们的draw ...

Updated "Remove Instances" on a Hierarchical Instanced Static Mesh Component to now properly rebuild the cluster tree, allowing “Get Instances Overlapping Box” to return correct results. Updated significance to now be correctly calculated when there are multiple viewpoints and significance is being so...

Hierarchical Instanced Static Meshes If collections of static meshes that have LODs are used, consider a Hierarchical Instanced Static Mesh. Figure 25:Sphere of Hierarchical Instanced Meshes with Level Of Detail. Like a standard instanced mesh, hierarchical instances reduce the number of draw calls...
