HI badmoodtaylor and SimoneT,
Both seems like good approaches, thanks for suggesting. I like the idea of Groups that get turned on/off, and I also like the idea of using the lerp function for easing.
However couldn't get either to work
badmoodtaylor, I may have the math wrong. I tried it several ways, how would I properly state "BlurEffect plus x"?
SimoneT, not sure what isn't working here. Pretty sure I have my global and instance variables set right, and I copied and pasted your values for lerp.
