Blue Skies Bark
This addon extends the functionality of the Treebark mod by adding bark from trees in the Blue Skies universe to the game. It requires the installation of both Tree Bark itself and the main Blue Skies mod from the Modding Legacy team.
When you debark tree trunks from Blue Skies, they start dropping as a separate resource. The amount of bark obtained can be configured in Treebark's configuration files. The acquired bark can be used in several ways: as fuel for furnaces, for crafting paper, or to restore the tree's original appearance - simply right-click on the debarked trunk while holding bark in your hand.
Important note: the minimum amount of bark required to restore a tree corresponds to the quantity that drops when debarking the corresponding block. For example, if an oak log drops 4 units of bark, that's exactly how many you'll need to restore it.
