A Procedural Island Generator Constructed with Geometry Nodes

Luke used Geometry Nodes to generate a stylized island and populate it with bushes, buildings, rocks  and extra, and provides a high-level overview of how he used Geometry Nodes to construct this generator.

A private Challenge influenced by Nordic, Scottish, and Irish islands. I needed to create one other randomly generated island by the contact of a button utilizing blender geometry nodes. Every island is exclusive in rotation, measurement, peak, and asset scattering.

Each mannequin is created by me and all textures are procedural.

Beneath is a quite simple breakdown of what’s occurring within the scene:

  • Every island begins life as a subdivided Airplane.
  • The airplane is then rounded off and a texture is overlaid which deletes components of the mesh. This texture is random and continuously altering.
  • The airplane is then extruded.
  • Some extra subdivision surfacing is completed and one other texture is overlaid which units the place of the vertices to create mountain-like constructions.
  • The ocean flooring is added as a subdivided dice. The peak of the dice is influenced by the proximity of the mountain-like object.
  • Then the ocean and the belongings are added and textured.

There was a number of different problem-solving occurring on this scene which was a number of enjoyable to work out. As an illustration, the dock all the time seems on the fringe of the island near the bottom grass level they usually seem extra usually if there’s a home or a lighthouse current on the island.

A extra detailed course of on how this was created might be discovered on my website.
