Trees

Trees

Places the Unity terrain-based trees at input positions.

Trees Output can output a single type of tree, as well as different trees from the list at random. The mode is switched by enabling/disabling Multi-Prefab toggle in Properties.

Main Properties:

  • Tree prefab slot (Multi-Prefab disabled): the prefab that will be used as a tree object.
  • Tree prefab layers (Multi-Prefab enabled): different prefabs that should be used at random.

Properties:

  • Color: tints output tree objects with selected color
  • Bend Factor: sets the trees bend factor that defines how trees react to Wind Zones
  • Multi-Prefab: toggles between single output or several objects (each will be selected at random).
  • Biome Blend: defines the way trees are placed on biome transition.

Height:

  • Relative Height: places the object on the ground level. Useful when creating a graph without a Floor. For custom objects height placement it's recommended to use Floor node instead.
    Effect1
  • Object Height: takes into account an object height that was set via Adjust or other node.

Rotation:

Note that Unity internally uses different types of trees: SpeedTree, Tree Editor tree, LOD tree, billboard (impostor) tree. Billboard trees could not be rotated and always face the same direction.

  • Use Rotation: uses object rotation that was set via Adjust or other node.
  • Terrain Normal: forces the object to be rotated along the terrain surface so that it's Y axis looks along the terrain normal vector.
  • Rotate Y only: rotates object along it's Y axis only.
  • Regards Prefab Rotation: will apply additional rotation stored in prefab. So if prefab has rotation 90 degrees Z axis (most common cases for 3DS Max objects) will rotate it properly when applying to terrain.

Scale:

Note that Unity internally uses different types of trees: SpeedTree, Tree Editor tree, LOD tree, billboard (impostor) tree. Billboard trees do not scale the main object, but scale only the billboard.

  • Use Scale: uses object scale that was set via Adjust or other node.
  • Scale Y only: scales object along the Y axis only.
  • Regards Prefab Scale: will apply additional scale stored in prefab. So if prefab has a scale 10, and scale 2 set via Adjust node, it will have a resulting scale 20.
