Driven Animation Sources - Head
The Head node processes the procedural head animation based on the input values, calculating the result on each execution and outputting it to an animation trigger.

Using Lerp
In additional to the values input from Vector2, you can use Lerp to design the range of random animations.
The Lerp (linear Interpolate) is a mathematical operation node to find an interpolated value between two inputs.
For example, create a 2 Stage Lerp node from the context menu Value > Lerp > 2 Stage Lerp to control the Focus Time.
The 2 Stage Lerp node provides 3 input ports: min, mid and max for three different ranges, input from the Float or Vector2 node.
It requires a parameter node to control the weight for output. You can create one by right-clicking on the empty area of the graph, and selecting Parameter > Create New from the context menu.
Name the new parameter and choose the float type. Click on OK.
Select this node to set a value ranging from 0 to 1 in the Variables section, to perform linear interpolation between the values from min to max. Once executed, the interpolated result is computed and sent to the connected nodes.
For example, create a 2 Stage Lerp node from the context menu Value > Lerp > 2 Stage Lerp to control the Focus Time.
The 2 Stage Lerp node provides 3 input ports: min, mid and max for three different ranges, input from the Float or Vector2 node.
It requires a parameter node to control the weight for output. You can create one by right-clicking on the empty area of the graph, and selecting Parameter > Create New from the context menu.
Name the new parameter and choose the float type. Click on OK.
Select this node to set a value ranging from 0 to 1 in the Variables section, to perform linear interpolation between the values from min to max. Once executed, the interpolated result is computed and sent to the connected nodes.
- If the value is set to 0, the result equals min.
- If the value is set to 0.5, the result equals mid.
- If the value is set to 1, the result equals max.
Make sure that the data are properly input in the Value nodes, before linking the Head node to an animation trigger node.
