@mushr0om what do you mean?

@Avro683Lancaster What layer is the rails on? if its ui or something it might not be rendered by the camera

@mushr0om The RailSpawner script is an attempt at using Object.instantiate to load the rails in. it didn't work.

@Avro683Lancaster What is the rail spawner script for? Check dev console to see if it has any errors

@WNP78 Didn't work

@WNP78 I shall try

@Avro683Lancaster hmm. Try clicking on the long wood track then do gameobject > break prefab instance

@WNP78 screenshot of what I have done is being uploaded to the post
None of the blue items load
all parts have the designer plugin and are saved to the mod

@Avro683Lancaster make sure the object which is not loading is a child of the object with the designer plugin, and make sure you save the scene objects every time you change something

@WNP78 I did that, but it doesn't load them into the designer. I am using Terrain, a directional light, which both load, and an obj with 3 children, which doesn't load.

Get all of your models etc as a GameObject in the scene, and add a DesignerPlugin script to it from the mod tools, then use the "Save Selected Scene Objects" button.
