The HISM instances work great on the editor and standalone game but after I package the project the instances disappear when I move closer. The HISM only seems to show LOD 2 while 0 and 1 are invisible. The far away LOD 2 instances also disappear when moving closer to the object but when viewed from distance, all LOD 2 objects are visible.
It’s impossible to use ISMs for this because they can’t handle LOD so I’m left with spawning thousands of static meshes.
I have solved this by Clear Instances at Event BeginPlay and adding them again. Just make a function that starts with Clear Instances and add the instances. This way you can use the function in construction script for previewing and then again on event graph.
