change/modify the properties that exists in sbsar material properties?

Hi all,
While I imported the sbsar that created from substance designer(SD), I need the button to controlling the parameter(exposed from SD).
So my question is that, is there any way to change the exposed parameter from substance designer? Please show me how?

Cheers

Is this what you want? https://support.allegorithmic.com/documentation/display/SD5/Expose+a+Parameter

A parameter exposed like this should show up in Unity.

Since this is the scripting forum, maybe you want to change the parameter from script? Take a look here
