“Difference” blending mode
Is there a way to get:
When two layers are identical, everywhere they are identical the alpha drops to zero (100% transparency)?

I’m not sure if I’ve ever tried this and I’m not in AE at the moment, but maybe using difference mode on the top layer, which will turn everything identical black, then precomposing those layers and applying an UnMult filter to the precomp, which will turn everything black transparent. If it doesn’t work, my apologies … running on very little sleep today. ;~)

You might look into the Difference Matte effect.

Doh! Good catch, Michael. Perhaps I shouldn’t try to answer questions when my brain is all mushy. lol
