here are some more pictures:
Spoiler: show
The mod converts randomly 9% of the rocks and 3.5% of the trees into christmas presents (on a map with 10000 rocks/trees). It adjusts for the number of trees/rocks so that even on maps with less or more trees the overall effect stays the same.
The size of the gifts scales with the amount of mass/power of the tree/stone that they replace.
The mod will be uploaded on saturday to the vault for everyone who wants to test it before: pm me
