Dr. Sassi,
Thanks for the prompt response!
It would appear that Craig inadvertently hijacked my question... that's OK though as I now have your original 2 projects as well as a project that wipes off with a vertex attribute. Neat!
Your original project with the Standard and Redshift versions is doing exactly what I was looking for... thank you! I will actually be rendering in both Standard for roughs and Redshift for finals, so 2 separate versions is great.
However, I am no closer to understanding what's going on so I might later recreate/build this effects than I was. It appears the Formula Effector you've provided is very different from the default Formula Effector... so I have zero idea on how you got there as well. I am also unclear on what the Colorizer is actually coloring. Is there a grayscale on my clones by default the that Colorizer is working on?
So... I'm reading my response above and it sounds ungrateful... please don't take it that way. I am just unclear on the theory (or buttons clicked) for what is going on.
Thanks for any clarification you or anyone else can pass.
