Editor - Script Interaction

I have a script that creates a heightmap terrain. I would like to be able to see this terrain in the editor so that I can place objects on it and whatnot. The mesh is created in the MonoBehavior:Start() function. I haven't been able to find the documentation on Script Editor interaction, can someone point me in the right direction?

Thanks,
Mortoc

 

Documentation is here: http://unity3d.com/Documentation/ScriptReference/20_class_hierarchy.Editor_Classes.html

Though unless you're modifying the mesh itself in the editor (seems risky to me) I don't know that that will help you much.

 

Thanks, thats what I was looking for.
