Path mode


Overview

Path distribution was introduced in Forest Pack 6, it enables you to distribute objects at regular intervals along one or more splines. The distribution remains fully parametric so you can easily adjust the spacing, offset rotation and more at any time.

This feature replaces the Distribute Along Spline feature found in the Tree Editor rollout in versions of Forest Pack prior to version 6.

Procedures

To add spline

  • Click on the  button and select one or more splines by clicking on them in the viewport

To delete splines

  1. Select the spline to remove from the paths list
  2. Click the  button.

To add multiple splines

  1. Click on the  button. 
  2. A scene explorer will open called Add Multiple
  3. Select all the splines you wish to add by holding down CTRL and clicking to select individual splines or using SHIFT and Click to select a range. 
  4. Click Add

To distribute objects at evenly spaced intervals along spline(s)

  1. Add splines to the Path List.
  2. Enable Spacing mode. 
  3. Adjust the distance between objects using the Spacing Value

To distribute objects on the vertices of along spline(s)

  1. Add splines to the Path List.
  2. Enable In Vertex positions mode.

To align objects to follow the direction of spline(s)

  • To rotate objects on the X axis to follow the path enable Follow Path > X
  • To rotate objects on the Z axis to follow the path enable Follow Path > Z

To offset items parallel to the spline(s)

  • Increase or decrease the Offset property.

To create a repeating sequence of items

  1. In the Geometry rollout, choose the order of items by moving them up and down in the stack using the arrow buttons. 

  2. Go to the Distribution rollout and enable Path Mode. 
  3. Add splines to the Splines List. 
  4. Change Geom. ID to Sequence.

Interface

Paths

The paths list allow to to select and manage the splines used in the scene along which items are distributed. Add and remove splines from the list using the buttons:

Add a single spline to the list
Delete the spline selected in the list

Open a scene explorer window and add multiple splines to the list


Geom ID

If you have more that one object in the Geometry List, this drop-down menu determines the order in which they are distributed along the spline. Use Sequence to loop through them in the order they appear in the Geometry list or use Random to shuffle the order. 

Spacing

In this mode items are positioned at regular intervals along the spline, defined using the distance paramter. 

In Vertex Positions

In this mode items are placed on a spline's vertices. 

Spline Offset

Offsets the items on the spline. Positive numbers move the items to one side of the spline, negative to the other. 

Follow Path

This options allow you to rotate the items to follow the path of the spline. There are separate controls for the X and Z axis.
