Join Chris Meyer for an in-depth discussion in this video Solving problems by using a second composition, part of After Effects Apprentice 08: Nesting and Precomposing.
Trish Meyer: If you remember, our goal was to create a movie, then rotate it, then have a Wave…Warp applied, and it was also trimmed down using a mask into a square shape.…Let's see how far we got at the end of the last movie.…I'll bring After Effects forward and remind you where we left off.…By only using one composition, we ran into a few problems.…I created my mask shape but when I applied the Wave Warp, it also affected…the edge of the mask.…When I look at the Timeline, I can clearly see that the mask renders first,…followed by the effects, followed by all the transformations.…
And I found that when I try to rotate the layer, it also rotated the entire…result including the mask.…So it's obvious that I can't get to where I need to be using one composition.…When you take one layer and spread it across two compositions, you'll have two…sets of masks, effects and transformations and then you'd be able to pick and…choose in which compositions certain operations happen.…So let's see how that works.…
The After Effects Apprentice series was created by Trish and Chris Meyer. These tutorials are designed for After Effects CS4 through CC, and can be used on their own or as a companion to the Meyer's book, After Effects Apprentice.
- Grouping layers by nesting and precomposing
- Identifying and solving render order issues
- Navigating composition hierarchies
- Editing a precomp while viewing the result in another composition
- Preserving the frame rate of a nested composition
Skill Level Intermediate
Q: This course was updated on 11/29/2012. What changed?
A: We added a new chapter, "Render Order Exceptions." It contains four new movies: Continuous rasterization, The Transform effect, Collapse transformations, and Compound effects. We also added a movie that shows our premium subscribers how to use the exercise files, including the new exercise files designed for After Effects CS6.
