Not all of the Modifier sliders seem to work for a given transform effect.

We are actively working on providing more explicit names for the transformation pieces that each slider adjusts, rather than the generic “Modifier” name currently in use.  Along with these more useful modifier names, users can expect non-responsive sliders to become tied to actual transformation parameters in upcoming updates to illumin8.
The settings icon on the start or home screen of the application also reveals some sliders that are currently nonfunctional and can be ignored or toggled away to hide by clicking the settings icon on the home screen again.
