这个FInstancedStaticMeshInstanceData 内部存储着一个 Matrix,也就是说,Add Instance 传入的 Transform 被转化成了 Matrix 并存储在内存中: USTRUCT() struct FInstancedStaticMeshInstanceData { GENERATED_USTRUCT_BODY() UPROPERTY(EditAnywhere, Category=Instances) FMatrix Transform; // ... }; 实际上,ISM...
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...

Learn to optimize a project through instancing with the instanced static mesh component in Unreal Engine.
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...
3.设置视口区域大小。这个大小会因为是否开启InstancedStereoPass而有所变化。 渲染静态数据 如果PrePass已经进行深度渲染,那么会先渲染Masked蒙版对象,然后渲染普通不透明对象。否则,先渲染不透明对象,再渲染蒙版对象。 渲染动态数据 与PrePass基本相同 BasePass采用MRT(Multi_Render Target)多渲染目标技术,从而允许Shader...
UInstancedStaticMeshComponent Similar to HierarchicalInstancedStaticMeshComponent but less optimized; used for rendering multiple instances of the same mesh. UInterpToMovementComponent Provides interpolated movement between points for smooth transitions. ULightComponent The base class for all light components...
New: Enabled custom export of navigable geometry for foliage with InstancedStaticMesh type. Bugfix: Streaming out of a level containing a RecastNavMesh instance no longer crashes the engine. Bugfix: A bug in editor-time navigation system, resulting in removing all the saved data in static ...
