Digital Creator School posts a look at one possible workflow for combining 3D and 2D elements in After Effects.
In this day and age, there is a multitude of ways to bridge the gap between 3D work and work in After Effects. Ae itself has Cineware as an easy way for blending 3D from Cinema 4D to Ae, replacing the deprecated 3D renderer in there. We also have the opportunity to use third-party 3D tools and plugins in After Effects. There are even a few live link plugins that let you work and sync back and forth.
All those methods aside, you can still use an older, but still useful method of manually managing your resources, showing a particular workflow for blending 3D and 2D effects from Maya to After Effects and back again. It is worthwhile to note that MASH in Maya has an After Effects live link plugin for both Maya and After Effects that syncs most everything that you would need to make motion graphics.
