UE 5.6 - Grass Overlapping Sphere Count returns zero [Reported]

Thanks @Kemichar.

It works fine for HISMs used for hand-painted foliage. There’s this PerInstanceSMData array in UInstancedStaticMeshComponent that gets populated in that case, but is empty in landscape grass HISMs. The overlap logic seems to depend on the array.

Yes, this functionality is vital for my project. That’s why I actually tried messing with the code, but its complexity just goes far beyond my understanding.

I submitted a bug report to Epic two days ago. All I can do is wait, I guess…
