Ideas, techniques, on graphical overlay to divide terrain in sections

Unity Engine

Hello,

I have a top-down rts style game and I want to “graphically” divide my terrain into large “jigsaw puzzle-like” pieces. I want all of the “sections” of the terrain to fit together, and by that I mean the graphical overlay sections (not the terrain itself).

So, essentially, imagine a square that is divided up into 100 pieces (like a jigsaw puzzle), where each piece can be curved at certain portions of it, etc, but they all fit seamlessly together.

For an example, you can see in this YouTube video around 00:14 to 00:25 seconds in, there is a blue line on the terrain. This is approximately what I’m trying to achieve:

How might I be able to achieve this?

One idea I had was to make a flat square “cube” in Blender, and use the “fracture” tool to fracture the cube into pieces. Then, import the fractured cube into Unity and using an “outline” addon from the asset store, apply the outlines to the cube cells. Then lay the cube on the top of the terrain. Not sure if that’s the best way to do it though, or if it would work.

Anyone have any ideas?

Probably something along the lines of a trail rendered i.e. some kind of fence or spline-based procedural geometry with a simple shader with a fade on it.

Hmmm, so kind of like what the “Mega-shapes” addon on the asset store does. How hard is it to do spline-based procedural geometry by yourself? Through code or is there a good tool? :hushed:

Thanks for the suggestion.

This was my first thought, kind of.an intersection boolean. Blender should have that. It’s been in Max since the original 3D Studio back in the 90’s.
