Requirements: Blender 4.2 LTS or newer. Scene generation and Cycles renders tested on 4.2 and 5.0.1. EEVEE has not been tested. Uses numpy, which is bundled with Blender. 8 GB RAM recommended (4 GB minimum).

Quick start (no scripting):

1. Unzip the download.
2. Open OuterSolarSystem_MHDINT.blend.
3. Press F12 to render the current frame, or Ctrl+F12 to render the animation.

Change the camera: go to the Scripting tab (the script is already open inside the .blend), set ONLY_SWITCH_CAMERA = "pluto" and press Alt+P. This does not rebuild the scene: it switches the camera and shows the objects that belong to that view. Camera keys: general, inner, kuiper, top, far, oort, pluto, ceres, eris, haumea, makemake, gonggong, quaoar, sedna, halley, jupiter, saturn, uranus, neptune.

Rebuild with your own settings:

1. In the Scripting tab, edit the settings at the top of outer_solar_system_v1.0.py. The main ones: the start date, the duration and speed of the animation, lighting, labels and orbit lines, RESOLUTION (all with comments in the file).
2. Set ONLY_SWITCH_CAMERA = None and press Alt+P. The scene is rebuilt from scratch.

Read the data: select an object named MHDINT_… and open Object Properties → Custom Properties. Values carry their source and say whether they are measured, computed or illustrative.

Performance: rebuilding takes about a minute (the Kuiper belt and the Oort cloud have many points). A still render takes minutes on a CPU; the default 50-year animation needs a GPU or a render farm.
