You can change the configuration of Entities (depending on the configuration file selected, this may include gender, skin tone and clothing, among other factors) and their ‘contour’ colour (the colour of Entities when rendered in full 3D).

To change the Entity options:

1. Select Tools > Options > Entity.
2. If you want to select a specific design of Entity:
   • Click the browse button to the right of the Entity Configuration File box.
   • Navigate to and select a configuration file (.cfg).
   • Click Open.
3. Select an Entity contour colour from the drop-down list.
4. If you wish to generate differently assorted characters each time you replay this simulation, check the box labelled 'Randomise character assignment on restart'.
5. Click Apply or OK to save your changes (‘OK’ will close the dialogue box).
