Procedural Modeling

Introduction​

Procedural modeling builds geometry from rules: modifiers, node systems, and generators that you configure and reconfigure. Parameters drive the result, so a scene stays editable while you change spacing, counts, and distributions.

Parameters over pushes

Numbers control the geometry. Change a value and the whole pattern updates.

Stay non-destructive

Apply a modifier only when the next step needs applied geometry.

Generate over real assets

Instance parts from your library so camera matching works against real geometry.

Key Concepts​

  • Modifiers
  • Geometry nodes
  • Parametric design
  • Non-destructive workflow

Workflow​

  1. Pick the generator: Array for repeats, Curve for paths, Geometry Nodes for rules that cover a whole scene.
  2. Set scale first: apply transforms on the source objects so spacing comes out in scene units.
  3. Constrain the output: limit ranges, scatter real library parts, and keep node trees small.
  4. Iterate live: adjust parameters against the camera view, then apply geometry only when an export or another modifier requires it.

Best Practices​

  • Apply scale and rotation before a modifier reads object transforms.
  • Name node groups by what they generate so the file stays openable under deadline.
  • Keep one generator per job. Split a scene into several small trees instead of one master graph.

Summary​

Procedural modeling keeps geometry adjustable: parameters drive repeats, paths, and distributions until you commit to applied meshes. Set scale first, generate against real assets, and keep each tree small enough to reopen and edit.
