1. download the newest release as a zip file puddler.js file
2. unpack the zip folder somewhere
3. mark all the spots where rivers can start in your worldpainter world with the CYAN annotation layer. Be generous, a 100×100 area is fine
4. in WorldPainter, on the top toolbar, center-right, open “run script” and select Puddler.js from the folder where you unpacked the zip file
5. Select your wanted parameters and run the script. Check “use Annotations” to get a preview of the rivers.
6. Inspect if you like the rivers and puddles (lakes)
7. Undo the script with ctrl + z
8. Edit the terrain, to control where the water flows and where lakes form
9. Repeat steps 5-8 until you are satisfied
10. Run the script a final time with “flood Puddles” and “apply Rivers” checked to apply water
11. Export the map to minecraft

• Max Puddle Surface: Lakes will stop growing if they reach this surface area and will not overflow and spawn new rivers. Smaller value: smaller lakes, rivers might not reach ocean
• Minimal River Length: Dont apply rivers that are shorter than this
• Spawn Probability: Chance for a river to spawn at a cyan annotated block.
  • 1000 = 1 block for 1000 cyan blocks will spawn a river.
  • 1 = 1 block for 1 cyan block will spawn a river
• Flood Puddles: Puddles (Lakes) will be filled with water
• Apply Rivers: Rivers will be filled with water
• Apply as Annotations: Rivers and Puddles will be annotated in Orange and Purple
• Ocean Water Leve: Rivers will stop once they reach this height. Should match your ocean level.
