Leaves mesh node

The Leaves mesh builder is intended to create leaves by creating surfaces on both sides along the path line.

Angle across

Specifies the starting angle of an imaginary path across the main path.

Angle along

Specifies the starting angle of an imaginary path along the main path.

Angle axis

Specifies the general orientation of the leaves.

Sides

Specifies the number of faces on imaginary path's length. This parameter is available when the Optimize faces option in the Optimization group is off.

Width

Specifies the width of leaf, or the imaginary path's length.

Scale proportionally

When on, the leaf width is directly proportionally to its length. The initial length is the length specified in the Path node. Accordingly, reducing the leaf length using Affect node or other influence, its width will also decrease.

Optimization group

Allows to optimize mesh.

Optimize faces

Enables optimization.

Face size

Specifies the face size during the building process.

Override steps

This parameter allows to enable the override steps, so it allows the user to change the number of polygons along paths.

Steps

Specifies the new step of the current path. This parameter is available when the Override steps option is on.

By Width Curve Points

With this option, the number of polygons along paths is equal to count points on the width curve if the Curve node is connected to the Width parameter. This option is available when the Override steps option is on.

Without central edges

When on, the central edge will be deleted.

Incremental angle group

Allows to set up the angles of incremental imaginary paths.

Angle across

Specifies the incremental angle of animaginary path across the main path.

Angle along

Specifies the incremental angle of an imaginary path along the main path.

Angle across map

Assigns a texture map from a selection dialog. After you make a valid choice, these buttons display the name of the bitmap or map. This button is labeled "None" until you choose a map. These settings help to create the unevenness on the edges of the leaves. The right connector allows to connect the UVW Mapping node to customize the UVW coordinates for Angle across map of received surface.

Scale angle

Specifies general scale of incremental angle.

Surface parameters group

Allows to set up surface parameters.

Mat ID

Specifies the material identifier. The right connector allows to connect the Chaos Material ID node to control the chaotic behavior of material IDs.

UVW Mapping

The right connector allows to connect the UVW Mapping node to customize the UVW coordinates of received surface.

Vertex color

Allows to configure the Vertex color parameters. The right connector allows to connect a Vertex color nodes.

Flip normals

It flips the direction of leaf surface normals. Accordingly, the front side of the leaves becomes the inside side.

2-Sided leaves

Generates a two-sided leaves. Used mainly for game development.

The right connectors allows to connect the Curve node to control the values of the corresponding parameters along the pathlines.

This builder creates the surface in the following way:

Imaginary paths grow in two opposite directions from each node point of the path. The paths grow at the particular angles (a) and (b) with a definite step (f) or (if Optimize is off) (e/d), turning at the angles (h) and (i) and moving as far as the distance (e). If Override steps is on, the steps (g) will be recalculated.

By setting up the appropriate parameters, the user can build a great variety of leaves.
