Tree

Trees are objects that can be placed in the world.

Tree Dialog

• ID: The editor ID for the object
• Trunk Flexibility: Controls animation of the root bone in a skinned mesh (horizontal only)
• Branch Flexibility: Controls animation of secondary bones connected to the trunk (horizontal and vertical)
• Leaf Amplitude: Amplitude of the swaying animation in leaf parts of the mesh
• Leaf Frequency: Frequency of the animation (how fast it moves)
• Tree Model: The model used for the object
  • Edit: Change the model
• Name: In game display name

Ingredient Production

• Ingredient: The ingredient item that is produced when the tree is harvested
• Harvest Sound: The sound to play when being harvested
  • Spring: Chance of harvesting during spring
  • Summer: Chance of harvesting during summer
  • Fall: Chance of harvesting during fall
  • Winter: Chance of harvesting during winter

Notes

• Flexibility/Amplitude/Frequency parameters are highly dependent on the structure of the specific mesh and must be fine-tuned on a case by case basis, although a good starting point might be 3 for leaf amplitude and 1 for leaf frequency.
  • Leaf Amplitude and Leaf Frequency parameters relate to 2D parts of a mesh that have been converted to BSLeafAnimNodes and vertex painted.
  • Trunk Flexibility and Branch Flexibility control animation of 2D and 3D parts of a skinned mesh (converted to BSTreeNodes). The Trunk is the root bone and can only move along the x and y axes (to prevent the tree flopping up and down), whereas Branches are the secondary bones and can move in all directions.
• Wind Speed is known to affect BSTreeNode animations, but may or may not also affect BSLeafAnimNodes.
• In the Special Edition version of the Creation Kit, there is a bug where references to skinned trees have oversized bounding boxes in the render window, making it difficult to select other objects when they are present.
  • This can be circumvented with the following ini tweak in CreationKitPrefs.ini:
