As it happens, I've taught a course called Understanding the Rendering Order that focuses on the sunburst Collapse switch (which is different in 2D vs 3D as well as Illustrator vs. precomps)
It always sounds so boring as a description, but a good understanding of the render order is the key to getting work done without pulling your hair out.Â
I just proposed teaching it for After Effects World in Seattle this Sept, so stay tuned on that. And I do have plans to turn it into a lynda.com course this fall.Â
about the breakdown - this year I started teaching AE in design school. learned so much by teaching since I wanted to be prepared
for every contingency. basically did a breakdown for all the Ai/Psd -> Ae Workflows and Scenarios.Â
if I didn't, than one student would say "hey!, it doesn't work!, its broken! theres a bug in my software" etc. etc, and I get nervous trying to figure out what the hell happened.
also you learn a lot from all the students ways of getting lost, I learned about how to stay on the right path in many situations.Â
if you liked that , you will be amazed about the breakdown I did for collapse transformations ;)
