Note about textures and crafting

--------------------------------
|

This mod is fully functional but does not currently have a crafting recipe or
|

proper textures. The airboat is available in the creative inventory.

It is currently a 'kit mod' for you to complete. The textures are templates for

you to add detail to.

detailed textures. It is currently a 'kit mod' for you to complete. The textures

are templates for you to add detail to.
|
||||
The airboat is available in the creative inventory or by using the /giveme chat
|
||||
command.
|
||||
|
||||
Usage
|
||||
-----
|
||||
Third-person camera mode is recommended when travelling for a better view.
|
||||
The airboat can be placed on any node, including liquids. It can land on, and
|
||||
will float in, a liquid.
