Connect nodes, adjust parameters and see the result update in your scene. Visual graphs for most jobs, a C# API when you need it.
200+ nodes in the box, from scattering to splines, meshes and physics queries.
Browse the node catalogA complete redesign of OctoShaper, in your browser. Build procedural 3D models as a node graph or as code, paint them by hand, and export glTF for any engine.
An early version that will change a lot. It is separate from the OctoShaper you can get today, which carries on as it is.
Connect nodes, adjust parameters and see the result update in your scene. Every graph is a regular asset in your project.
New to OctoShaper? The getting-started tutorial builds a reusable graph step by step, with a video companion.
Layouts, buildings, vegetation, splines and meshes, each generated by a graph.
Walls, towers and houses placed by the graph, while you control the overall shape.
Floors, windows and roofs from your own modular pieces, stacked by the graph.
Grass and small plants over large areas, drawn with GPU instancing.
Bridges, walls and paths: your meshes placed and instanced along a curve.
Points sampled on meshes and terrain, culled by slope, with props that sit on the ground.
Landmarks like this arena, generated from a few parameters instead of modelled.
Use the OctoShaper skill to make a stylised rock graph. Expose the seed, point count and roughness.
I'll look up the nodes I need, then build and render the graph.

StylisedRock is saved, with Seed, Point Count and Roughness exposed.
Drag a height, a width or a radius with scene handles, and draw splines straight onto your level. The graph follows every move.
Try ideas in an isolated stage without touching your open scene. Pin the preview to any node, and another node's points and edges as gizmos.
Drop one graph into another like any node, preview included. Each copy gets its own parameter values.
