Unity provides a tool called Tree Editor that lets you design trees directly within the editor. This is very useful when you want to create detailed forests and jungles with different tree types and variations.
This section of the manual explains how to use the Tree Editor. Use the navigation column on the left-hand side of the page to view topics in this section.
You can use SpeedTree Modeler from IDV, Inc. to create trees with advanced visual effects such as smooth LODThe Level Of Detail (LOD) technique is an optimization that reduces the number of triangles that Unity has to render for a GameObject when its distance from the Camera increases. More info
