In-editor IID assignment logic

Just wondering how the IID's are assigned to objects that are already in the layout at startup.

It seems that they are assigned based on the order that they were loaded into the layout in the editor, which would be the same as if they were loaded by an event.

eg. if there are 4 instances of an object on the layout from left to right, and the first(from left) was created first, the second second etc. Then the IID's from left to right would be 0,1,2,3.

However if the first created was the right hand object and then on from right to left; the IID's would be from left to right: 3,2,1,0

Is this correct?

Yes it's based on the order of creation. You can use UID (all objects) in the editor to work out in which order they were created as IID is hidden.

Thanks, that's what I figured
