LODs, Export and Baking

1. Wire an LOD Table

1. Add LOD Table to the tree graph. Add an Integer variable named exactly LOD, default 0. Connect GET LOD.Value to LOD Table.LOD.
2. Set TrunkSides to 12, 10, 8, 6; BodySegment to 0.2, 0.35, 0.55, 0.8; LeafCount to 8, 6, 4, 3; LeafScale to 1, 1.1, 1.25, 1.45. The four entries mean LOD 0, 1, 2, 3.
3. Connect TrunkSides → Skin.Sides, BodySegment → Skin.Segment, LeafCount → Foliage.Count and LeafScale → Foliage.Size. Replace earlier wires on these numeric inputs.
4. Use the preview LOD control to inspect all four levels. Look for angular trunks and sparse canopy. Restore LOD 0 for close-up review.

2. Export a Static Mesh

1. Connect both wood and Foliage.Instances to Plant Output through the final join. Set graph materials and atlas settings before export.
2. Click graph toolbar Export Mesh. The export realises leaf instances into mesh geometry and creates four LODs.
3. The resulting SM_<GraphName> asset is created beside the graph. It can be used in standard Static Mesh placement and scattering workflows.

3. Bake an individual actor

1. Select the Procedural Plant Actor with the desired individual overrides.
2. In its component Cooking controls, click Bake. Use Cook Policy → Use Baked Mesh for a fixed plant.
3. The bake stores wood plus separate foliage prototypes and transforms. Save these generated assets with the actor's level.
4. Bake again after graph, seed, density or material changes. Test the intended map in a packaged build before shipping.

Large modelled canopies and repeated runtime rebuilds can be expensive. Measure frame time, memory and export size in the intended scene. Nanite does not remove foliage overdraw, material cost or generation cost.
