Bring in solid/null faces of cubes from C4D to After effects
Hello,
I have a scene of 6 cubes inside Cinema 4d. The cubes each rotate -180 degrees. I would like to be able to bring each of the cubes faces into after effects as solids/null objects – so I can use the data for a transition between two scenes.
The idea is that ‘scene A’ is full screen (1920 x 1080) and then that scene transitions off by the 6 cubes rotating and the front faces (which formed ‘scene A’) rotate to reveal new sides of the box which form ‘scene B’.
I’ve tried adding object buffers/external compositing tags in C4D but when I bring this into after effects it only has 1 face of each cube (not all 4) and the solid appears to be in the middle of the cube rather then on one of the cubes faces (I assume this is because that is where the anchor point is on the cube inside c4d?)
Any help would be greatly appreciated.
Kind regards,
James -

I think the easiest way to do this would be to break up the cubes into individual polygons and assign each polygon it’s own external compositing tag.
Here’s how you’d do it for one cube:
1. Make editable if necessary and select all polygons;
2. Go to Mesh>Commands>Disconnect and click the gear icon to the right. Uncheck “preserve groups” and click OK;
3. Run Mesh>Conversion>Polygon Groups to Objects.Now you’ve got separate objects for each face, but you still need to situation the axes accordingly so the solids will line up in AE.
4. Select all of the sides objects and run Mesh>Axis Center>Axis Center;
5. In the Alignment section of the dialogue check the alignment box, set the axis to Z, and set Alignment to “Normals”Now you just have to add the external compositing tags and save out the 3D data.
