It is important to note that the editor must be closed for the field editor to work. This has the unfortunate consequence that inputs might be caught by other things, so be careful.
- Don't Paint - Turn off field painting.
- Paint Fields - Enable field painting.
- Erase Fields - Enable field erasing.
You can paint either only C (creeper) fields, AC or All (both). When choosing field direction, the center option is a pin field, which lets creeper enter but not leave - with the exception of wind, which does not respect pin fields. The option with the mouse icon will paint fields based on how you move your mouse.

This button lets players turn off field visuals. This cannot be used in the editor, because the existence of images is impervious to proper functioning of the map after it is finalized.
