 To turn on LOD for a tree, select the [[tree_generator|Tree Generator]] and tick the "​Enabled"​ property in the [[tree_generator#​dynamic_lod|Dynamic LOD]] property group. You can also set the number of LOD levels with the "​Number"​ property. To turn on LOD for a tree, select the [[tree_generator|Tree Generator]] and tick the "​Enabled"​ property in the [[tree_generator#​dynamic_lod|Dynamic LOD]] property group.

-When you do this, an LOD control will appear in the bottom-left of the [[tooltree_window|Tree Window]], shown to the left. By default, the slider is in "​Manual"​ mode. If you drag the arrow up and down in the LOD control, the tree will dynamically change LOD. You can see the polygon counts update as this occurs.+When you do this, an LOD control will appear in the bottom-left of the [[tree_window|Tree Window]], shown to the left.

 Clicking the "​..."​ button at the bottom of the LOD control allows you to switch the LOD mode from "​Manual"​ to "​Screen Area." This will disable any mouse input on the control, but the tree will dynamically change LOD as you move the camera nearer or farther away. Clicking the "​..."​ button at the bottom of the LOD control allows you to switch the LOD mode from "​Manual"​ to "​Screen Area."

-To control how many parts are removed at a global level, use the [[curves#​lod_curves|LOD curves]] property in the [[tree_generator#​dynamic_lod|Dynamic LOD]] property group in the [[tooltree_window|Tree Generator]]. With these curves, you are controlling the reduction over the course of the tree's total LOD transition. There are a number of these properties, to control the reduction of different geometry types in the tree: branches, leaves, decorations,​ etc.+To control how many parts are removed at a global level, use the [[curves#​lod_curves|LOD curves]] property in the [[tree_generator#​dynamic_lod|Dynamic LOD]] property group in the [[tree_window|Tree Generator]].

-Mesh LOD levels are set up in the [[toolmeshesbar|Mesh Asset Bar]].

-Similar to segment reduction, mesh LOD can cause visible pops you need to be careful to avoid. This is especially so if you are using [[kcmesh_anchors|mesh anchors]] to place children. If the mesh anchors move with LOD, the tree might change drastically.+Similar to segment reduction, mesh LOD can cause visible pops you need to be careful to avoid.
