I imported a solid blender model but it's in pieces?

So I made a bridge for my game in blender and imported it, same as normal and the model has
been made with the same method, nothing new or special or anything different.

I bring it into Unity and I noticed that the model has some items attached to it in the hierarchy:

Now in Blender, the bridge is one entire object, it’s not several small pieces stuck together or anything, it’s literally one object, so I’m not sure why it’s suddenly doing this.

Also I can’t click on the model itself in the scene and can’t move, rescale or rotate it unless I select it in the hierarchy.

Any and all answers would be greatly appreciated :slight_smile:

You probably have more than 65k of vertices and therefore it splits the model into smaller pieces.
