How to overload operator == for (TArray)?

not like that, you need to get location first on them.
Location on staticmesh01 02 and so on, you are getting the location on world like this, you need the reative location of items.

Get relative location on them and with that transform. Without getting location you are getting world coordinates on the meshes that are offset really from the main component, and you are getting the main component coordinate because world does not know yet about your extra items.

Makes it easy with Vecotrs, I don’t use Ftransform.
