 ==Seam Blends== ==Seam Blends==
 Seam blends are the small piece of geometry that hides the intersection of a branch to its parent by blending the parent material over top of the child branch. This is done using vertex alphas to fade it out. If the engine does not support per-vertex alphas, or if z-buffer problems are causing the seam blends to flicker, then you may disable this. Even without per-vertex alphas (and thus a hard line where the material changes), the blend pieces usually add to the realism of the tree by hiding the actual branch intersection. Seam blends are the small piece of geometry that hides the intersection of a branch to its parent by blending the parent material over top of the child branch.

 +==Leaf References==
 +Leaf References are null objects in the correct position and orientation for each leaf. These can be used to populate the leaves with higher quality meshes at runtime, or perhaps for use with mesh instancing.
