Get Instances Overlap returns overlap outside of the collision bounds.
This effects the Instanced Overlapping Box and Sphere. It is also reproducible with engine assets replacing the Fencing mesh.
I have seen a few people having strange results when using this blueprint feature but I haven't seen a solution. My current project makes use of this a lot and with certain meshes the results seem to be different to what I am expecting.
I decided to create a new project to test this out so hopefully someone from Epic can have a look for me, I can upload this project if you need it.
1. Open the attached test project
2. Go to the Toolbar > Simulate
3. Select the Sphere
4. Use the translate widget to move the sphere towards the other (Fencing) object slowly until the Print String reads 1 (overlap)
Results: Before the sphere gets to the other object, the Print String will read 1 (which means the Instanced Overlapping Sphere is registering a overlap with the fence mesh.
Expected: For the Instanced Overlapping Sphere to only register an overlap when it is touching/overlapping with the instances collision.
