Generative Helper Methods for Blender 3.5

Wth is this?

Working with Python in Blender can be hard. There are a lot (and I mean a lot) of extra code to write that I felt could be abstracted away. So I wrote a couple classes with a few helper methods to simplify this.

Please note that these probably will change and be extended as I learn more generative techniques etc. But I think it’s a good starting point for now.

Please note that this library only works in newer versions of Blender (3.4+ I believe) that contains Python 3.10+.


There are two main elements that you most commonly work with when programming generative art in Blender:

  • Scene
  • Object

These are the two classes that this library is built around.


When starting a new generative project, there are stuff that I find myself doing over and over and over. Some examples:

  • Delete all objects / meshes by type everytime you run the script
  • Delete all materials everytime you run the script
  • Automatically render a PNG
  • etc.

Here’s an example of a basic setup.

# Example scene

scene = Scene()

  ["cube", "sphere", "cone"], # object types to be deleted on script re-run
  ["toon"], # materials to be deleted on script re-run
  "#EBEBEB" # world color


Working with objects / meshes in Python can also be difficult. That’s why I wrote the Object class. Some examples of what it can do:

  • Set the scale of an object
  • Set the position of an object
  • Set the rotation of an object
  • Set the material of an object
  • etc.

Here’s a basic example of creating a cube of a certain size, position and rotation.

# Example object creation

obj = Obj(
  "Cube", # object type
  "toon", # material name
  [1, 2.5, 2], # size x, y, z
  [2, 2, 0, 0], # position x, y, z, z-extra (z + n)
  [15, 12, 9]
