I just toyed around with the Nature Terrain Generator and the Multi-Duplicate tool a little and I have 2 points.
1.) Is there a way to incorporate the bonus textures into the script for making pathways?
2.) Can the "Multi-Duplicate Tool" rotation logic be incorporated into the Terrain Generator morphing script? It would be great to be able to create winding paths using tiles that remain connected at the seams.
Here is a rough project I made using custom textures and the path. it could have been done in half the time and less than half the effort if rotation morphing could have been added to the Terrain Generator.
