Proportional
The Proportional mode generates nodes for each parent relative to the parent's length. Nodes are generated in random locations with random orientations. This mode adapts to the size of the parent, making it suitable for randomization and cases where parents are of varying sizes.
In the image below there is a series of trunks of varying lengths. The branches all use the Proportional generation mode. Notice how short trunks have fewer branches than long ones. Also notice that every trunk gets at least one branch, no matter what.
Note
Interval mode is almost always a better choice than "Proportional" mode.
Each of this generation mode's properties is described below.
Number
Sets the number of nodes generated on a parent of average length (longer parents get more, shorter parents get less).
Jumble
A variance is placed on each node's orientation in order to achieve a more natural and random appearance.
Sweep
Specifies an arc around the parent node where nodes are eligible.
Roll
Each node is rotated this absolute amount from its computed angle.
Favor Splits
Positions the generated nodes on major bends or jinks. Hint: This is useful when trying to recreate the natural look of a branch splitting.
Align style
When "Align" is enabled, generated nodes attempt to roll their initial orientation skyward as much as they can, according to the following options: |Individual|Each node rolls skyward independently.| |Group|All of the nodes in the group roll skyward together.|
Align
This option toggles the skyward rolling behavior described above.
Shared
The "Shared" properties are common to all generation modes and are documented here.
