Currently boxes, spheres and loaded URLs show s with a fixed name like “Box”, or the FBX name only. There does not appear to be a way to rename them, e.g. in “entity Properties” or by things like a right click on them in edit mode.
When you have very many such entities called “Box” and FBX meshes are reused many times, this is problematic. Can a rename of an entity be added soon please?
