I Try add HISM to Array and add instance from loop.
In Content Examples in BP_Random_Meshes this BP work with StaticMeshes
If I try replace this static meshes by HISM it compile fine. But if I choose Static Mesh in HISM props UE crash with error
error look like this
Assertion failed: (void*)((&ElementData[InstanceIndex]) + 1) <= (void*)(InstanceTransformDataPtr + CurrentSize) [File:D:\Build++UE4\Sync\Engine\Source\Runtime\Engine\Public\StaticMeshResources.h] [Line: 1186]
Can you provide the entire crash, not just the last line?
