Blueprints/ko

Blueprints, also known as ghosts are semi-transparent ghost models of buildings. They appear before their building is completed, and resources are added to these blueprints in order to add on to the building while it is being built.

Blueprint Variations
There are buildings that can have their type changed once the blueprint has been placed by pressing the  key on them, here are some of them:
 * Small Stick Holder becomes a Large Stick Holder
 * Small Rock Holder becomes a Large Rock Holder
 * Small Log Holder becomes a Large Log Holder
 * Tree House, Alpine Tree House, and Tree Platform will have the option to remove, or keep the climbing rope
 * Defensive Wall can have doors added to the wall
 * Custom Wall can have wall sections changed to a door or window

Positional Variations
There are buildings that change types when they are placed in certain positions such as:
 * Wall Weapon Rack will becomes a Ground Weapon Holder if aimed at the ground
 * Platform will become a Cliff Side Platform when placed against a cliff
 * Animal Trap will be a Fish Trap when placed in water

Changing Blueprint Colors
In the options menu under gameplay you can change the color of blueprints as well as their opacity. The colors you can select are white, blue, and green (probably more).

Known Bugs

 * Very rarely when a blueprint is placed, it may completely vanish and the marker as well. This can be irritating because in the bottom left of the HUD shows resources needed for that specific blueprint that disappeared.
 * When building near the big hole, defensive wall blueprints can glitch, making them rise 20+ logs high, and be unremovable by usual means (tested near small river at direct crater side)
 * When you set a blueprint on the bottom of the ocean below the yacht the blueprint may be "stuck", you can't build on it or delete the blueprint.
