frustrating, because it would be nice to apply a global Effects filter to the whole
Precomp at once, it actually makes perfect sense - remember that when
Collapse Transforms is functioning all it's really doing is behaving like all its
layers are actually still present within the master composition having been
grouped together as one layer. If you wanted to apply an Effect to the group,
you'd have to apply the Effect to each layer within the group individually. When
you add an Effect to the Precomp, you're reverting it to Standard Nesting
mode.
Likewise, if you activate the Precomp's Blending Mode you're effectively
overriding all the group's individual Blending Modes and again reverting the
Precomp to basic Nesting.
Layers - Part 2: Taking Control of Your
Composition
Pulling it all Together
Precomping's ability to create groups of associated layers, and apply those
Precomps in two different modes, took After Effects to its next level. It opened
up a wide palette of 'free-form' design tools encouraging artists to design as
they build.
The WONK TV On-Air ID package's design was almost completed in the last
section, but as all artists know - their work is never complete. The logos still
need animation, effects applied, and additional elements to finish the whole
project. The package won't be truly complete until we use some of the more
advanced compositing features of After Effects: Parenting, 3D Layers and a
simple Shadow effect.
Parenting is one of After Effects' most simple yet powerful functions - attaching
a layer or layers to another layer. This is more like the grouping function many
other programs offer. But unlike grouping, where all layers operate in concert,
Parenting allows each Child layer (layer connected to the Parent) to still perform
individually.
