What I meant was that at frame 0, layer 1 would be 100% and layer 2 would be 100%. At frame 20, layer 1 would be 110% and layer 2 would be 120%. At five seconds, Layer 1 would be 200% and layer 2 would be 400%.
Except I have ten layers, all at different rates.
I figured it out. I had to use expressions, and it wasn’t obvious.
