Hello!
I’m looking for a way to calculate a tight FBox around a StaticMeshComponent that rotates with the component, keeping the same volume and orientation.
Unfortunately, this capability is not available for FBox, which by nature is an Axis-Aligned Bounding Box.
For anyone looking to do something like this, I ended up using UStaticMeshComponent::OverlapComponent().
Code for overlapping a staticmesh with a foliage instance bounding box:
FCollisionShape QueryBox = FCollisionShape::MakeBox(InstanceBox.GetExtent());
return MeshIn.OverlapComponent(InstanceBox.GetCenter(), FQuat::Identity, QueryBox);
