Description

An ambitious 3D visualization project where GPT-6 Astra generates and iterates on a furnished family home in Blender using the Python API. The pipeline includes floor plan design, geometric modeling of custom furniture, cinematic Cycles rendering, and an automated export to an interactive Unreal Engine 5 walkthrough with functional objects.

Prompt

Design a beautiful house with minimalist but highly detailed furniture and a nice garden. Make the scene cinematic, with considered lighting, materials, and time of day. / Make it golden hour. We should see the sun, and the house should be in the middle of a viridian forest. / I like the minimalist, modern style, so keep that while we grow the house to be much more livable. Draw me a floor plan first. We’ll validate and evolve it from there. / Keep the current scene as a backup, then build the updated house in Blender. Iterate until the house, furniture, and garden are detailed and the geometry is correct. Once we validate it in Blender, we’ll export it to Unreal Engine 5. / Make the lighting quieter, warmer, and more accurate. Improve how the materials respond to light, and add dishes and everyday objects so the house feels lived in.
