Spline Instantiate component reference

Use the Spline Instantiate component to instantiate GameObjects on a spline.

Property	Description
Container	Select a GameObject that has an attached Spline component you want to instantiate GameObjects or prefabs on.
Items To Instantiate	Create a list of GameObjects or prefabs you want to instantiate. For each element in the list, select a GameObject or prefab, and set a probability for that item to instantiate on the spline.
Up Axis	Select the axis instantiated items use as their up direction. The y-axis is the default up direction.
Forward Axis	Select the axis instantiated items use as their forward direction. The z-axis is the default forward direction.
Align To	Select the space that instantiated items orient to. The following spaces are available: Spline Element: Align instantiated items to an interpolated orientation calculated from the rotation of the knots closest to where each item instantiates. Spline Object: Align the instantiated items to the orientation of the target spline. World Space: Align instantiated items to world space orientation.
Instantiate Method	Select how to instantiate items on the spline. The following instantiate methods are available: Instance Count: Instantiate a number of items on the target spline. Spline Distance: Instantiate items separated by distance intervals measured along the spline. Linear Distance: Instantiate items separated by distance intervals measured linearly in world space.
Count	Set a number or an inclusive random range of items to instantiate. This property is visible only when you select the Instance Count instantiate method.
Spacing (Spline)	Set the distance interval to instantiate items at. The distance is measured along the spline. You can set an exact distance or an inclusive random range of values. This property is visible only when you select the Spline Distance instantiate method.
Spacing (Linear)	Set the distance interval to instantiate items at. The distance is measured linearly in world space. To instantiate as many items that can fit on the spline without overlap, select Auto. This property is visible only when you select the Linear Distance instantiate method.
Position Offset	Enable to instantiate items at a position relative to the spline.
Rotation Offset	Enable to instantiate items with a rotation relative to the original GameObject.
Scale Offset	Enable to instantiate items with a scale relative to the original GameObject.
Override space	Enable to apply the offset to a coordinate space you select. If you don't enable Override space, the offset applies to the coordinate space you set Align to to. This property is visible only when you enable Position Offset, Rotation Offset, or Scale Offset.
X	Set the offset's x-axis value. You can set an exact value or an inclusive random range of values. This property is visible only when you enable Position Offset, Rotation Offset, or Scale Offset.
Y	Set the offset's y-axis value. You can set an exact value or an inclusive random range of values. This property is visible only when you enable Position Offset, Rotation Offset, or Scale Offset.
Z	Set the offset's z-axis value. You can set an exact value or an inclusive random range of values. This property is visible only when you enable Position Offset, Rotation Offset, or Scale Offset.
Auto Refresh Generation	Enable the automatic regeneration of instantiated items when you change the spline or its instantiation values.
Randomize	Regenerate all values set to random ranges, and then instantiate items again.
Regenerate	Instantiate items on the spline again.
Clear	Remove all instantiated items from the spline.
