Set Driven Keys

Set driven keys provide an easy way to create object interactions without using the XPresso Editor directly.

A set driven key is a relationship where one parameter controls another. For example, suppose you want a door to open and close automatically as a character enters a room. The character’s position can be used to control whether the door is open or closed. The object parameter that does the controlling is the driver. The parameter that is being controlled is driven. Almost any kind of set-driven relationship is possible, making it easy to manage complex motions or objects.

To create a set driven key:

Decide which parameter is the driver and which parameter is driven (the driver controls the driven parameter).

Set the driver as follows:

Set the driven parameter as follows:

When selecting the driver and driven parameters, you can click individual parameters or parameter groups.

Relative Driven Keys

There is a second variation of set driven keys: Relative driven keys. These allow values to be set directly or with a range mapper node that is created automatically. In both cases the Input Upper, Input Lower, Output Upper and Output Lower parameters are adjusted accordingly.

To create a relative set driven key:
