Right now the code is like this:
public ToonDetailerVolumeComponent()
{
displayName = "Toon Detailer"; //displayName is marked as obselete
}
Couldn't find anywhere how and where should the new attribute be used.
[CS0618] 'VolumeComponent.displayName' is obsolete:
'Use DisplayInfo attribute to define a display name instead. #from(6000.3)'
