Twig

In order to scatter twigs and leafs in a tree, a particle system is used. The twig operator creates a twig object that can be set as dupli object in that particle system.

The operator can be found in the Tools panel under the tree category.

After clicking on the operator button, you can tweak some parameters:

• seed: Controls the pseudo-random list that the addon uses. Two different seed will result in two different twigs.
• length: Length of the core branch of the twig.
• iterations: grow iterations applied to the core branch of the twig.
• radius: Width of the branches.
• randomness: How chaotic the twig is looking.
• split_proba: Probability for a branch to split.
• offset: steps in the core branch that wont have a split.
• gravity strength: Amount of downward attraction.
• leaf type: Type of leaf to scatter in the twig.
• leaf_size: Size of each leaf.
• leaf_proba: probability for a leaf to be created. Higher value means more leafs.
