Foliage & Trunk Parameters

This section covers the customization of leaves, flowers (including fruits), and the main trunk/branch structure.

Leaves

The Leaves menu allows you to set parameters related to density, orientation, and scale. Note that the available settings change depending on your generation mode.

Fast & Accurate Modes

• Leaves Density: Regulates the overall density of the foliage.
• Distance Min: Suppresses leaves that are too close to each other to prevent overlapping and limit polycount.
• Leaves Random Scale: Sets a minimum and maximum random scale for the leaf assets.
• Alternating & Random Rotation: Adjusts the distribution and orientation of leaves along the branches.
• Inclination: Controls the leaf angle relative to the branch.
• Offset: Creates a distance between the leaf and the branch surface.

Precision Mode

• Density Radius Based: Automatically adjusts leaf density based on the thickness of the branch.
• Alignments: Specialized toggles to align leaves with the Branch normal, Global Ground (Z-axis), or the Target surface.
• Scale & Local Offset: Fine-tune the scale and position of assets along the local axis of the branch.

Flowers & Fruits

The Flowers menu functions similarly to the Leaves menu and is used to manage both flowers and fruit assets.

Fast & Accurate Modes

• Flower Probability: Controls the chance of a flower/fruit appearing at any given point.
• Random Scale: Randomizes the size of the flower/fruit assets.
• Rotation: Adjusts the local tilt. For falling assets like wisteria or heavy fruits, it is often necessary to orient them towards the Global Z-axis.

Precision Mode

• Animation: Specifically available in Precision mode to add dynamic movement to flowers.
• Advanced Alignment: Just like leaves, flowers can be aligned to the branch, ground, or target surface for perfect positioning.

Trunk & Branches

This menu defines the diameter of the trunk and branches, as well as their visual appearance through materials.

Main Parameters (Fast & Accurate)

• Trunk & Branch Radius: Independently set the thickness of the main trunk and the secondary branches.
• Procedural Bark Material: By default, branches use a procedural shader where you can adjust Luminosity, Contrast, Saturation, and Tint Intensity directly from the N-Panel.

Using Custom Materials

If you wish to use your own textures for the trunk:

1. Assign your material in the Material slot.
2. In your Shader Editor, use an Attribute node.
3. Important: Set the attribute name to UVs (case sensitive) and connect it to a Mapping node to ensure the textures wrap correctly around the generated branches.

Precision Mode: Branch Profile

• Auto Radius: Merges branches together where they intersect, creating a more organic, flared base for the trunk.
• UV Scale: Quickly adjust the tiling of the bark texture without entering the Shader Editor.
