Installation involves downloading Blender from blender.org and running it on macOS. Users can send prompts to control Blender's Python API, such as rendering scenes or adding elements.

The process was demonstrated with prompts to create a scene of a pelican riding a bicycle, followed by enhancements like backgrounds and effects. The images are generated through API calls, with costs estimated at $4.24 using gpt-6-astra.

This setup allows engineers to automate and script Blender tasks using language models, integrating visual content creation into workflows. It simplifies the use of coding agents for 3D rendering and scene composition.
