I have a number of custom sliders installed, but when I go into CAS I do not see all the sliders, why ?
To unlock the ability to have more than the EA Standard number of sliders, you must be running the custom version of CAS provided by MasterController.
*By default, custom CAS is only called when you use the "NRaas \ Master Controller" interactions directly.
If you attempt to run CAS from "Edit Town", you are running the EA version of CAS, which does not handle more sliders properly.
*You will need to install the Integration module, an optional component of MasterController, to unlock that capability.
*Integration will also replace the Shift-Click "Edit Sim in Create A Sim" interaction with custom CAS, allowing you to use that interaction as well.
