Setting up tree LODs

PROCEED WITH CAUTION

Unfortunately the billboard system that we used to use was supremely inefficient. So now tree impostors are tree LODs. Sorry about that.

Before you set up tree LODs, you need to have an low-poly version of the tree that you wish to use.

Trees are set up like this:

. Workspace
└ Trees
  └ OakTree
    ├ TreeModel
    │ ├ Trunks
    │ └ Leaves
    └ LOD
      └ TreeModel
        ├ Trunks
        └ Leaves

OakTree.TreeModel must have a tag called Tree. This allows CollectionService to get the tree model and index it for Luatri. OakTree must have its PrimaryPart set to OakTree.TreeModel.Trunks.
