Triggering two blend shapes with one controller

[roco7]

Hi ,

I nee help writing an expression that I can trigger two different blendshapes.

My controller is limited in translateY from 0 1 so from a value of 0 to 0.5 I need the controller to turn on blendshape1. From 0.5 to 1 I need it turn on blenshape2. So when the translation for my controller is set to 1 both of the blenshapes should be turned on.

Hi roco,

What you're asking can be achieved with Driven Keys, this tool allows to control many attributes with one attributes, thus you can define a value for each controlled attributes depending on the value of the controller's attribute.
Here is a demo showing you how to achieve it with 2 blendshapes and a circle controller moving on X axis from 0 to 1.
Don't forget to click the Key button to set a Driven Key.

Take note that in this example the first blendshape is set to 0 when the controller is on 1 so you can skip this step.

Have a nice day,
Mehdi
