I have some boxes created in AE 3d space and have precomped it.Then I switched on the collapse/transformation button to pop it back out to boxes. The goal is to have some smoke fly around the boxes.
Now the question is I am trying to use this precomp(boxes) layer as the obscuration layer in Particular like you normally would with any other flat plane with 3d layer turned on. However, the boxes layer does not behave like the flat 3d layer. So ultimately, does precomp layer work as an obscuration layer?
