View Full Version : after effects vs digital fusion question
10-08-2003, 02:25 AM
in digital fusion when you have to combine two alphas at varying percentages and isolations (sub and add), you use channel booleans.
In after effects how do you accomplish the same thing with out destryoying your rgb layer.???????

ummm... I dont see what it has to do with destroying rgb info. We're talking strictly alpha here, so its a seperate chanel altogehter.
In AE, combining those alpha's would probably be done with precomps (nested compositions). I am not experience in that area though... but I'm pretty sure thats right.

precomps are one way,
but it turns out it' has to do with layering, and some effects plugins

You'd use compound arithematic
