How to merge or group 3D layers?
So I'm trying to create a building in AE that has a bunch of storeys that I want to be 3-dimensional.
I'm new to this tool, right now I found no other way but to copypaste the stories, but I now want to duplicate and rotate the entire front that I created to make the other sides of the building.
Is there a way to group or merge all those 3D layers and maintain 3D edit mode, but for the whole side?
I tried precomposing but that turns it into a flat shape.
