Japanese Garden Path Tool

Over the summer of 2026, I wanted to go into a kind of procedural generation I had only done from tutorials before: generation along a curve! I was inspired by Japanese tea gardens, and how they naturally transition from pathways to stairs to bridges. So I created a tool that takes the angle of the terrain below it between each point and the distance between each point and the ground to automatically place the correct path types along the curve!

Here is a quick video of the tool in action:

Within the tool are essentially three separate tools: One for the path, one for the short bridges, and one for the large bridges.

For both types of bridges, the planks are procedurally generated, as well as any accompanying geometry!

The stone path tool automatically places fences with breakup and variation alongside both sides of the path! In addition, the smaller cubes scattered alongside the path stones are essentially points where plants, pebbles, etc. could be placed procedurally.

I had a lot of fun with this project, and it served as a valuable learning experience on how to make different HDAs work together!
