To bring animation from Blender to After Effects, I have used a simple JSX export plugin, to get the camera, lights and selected Empty / Null data. It worked perfectly and I was surprised how easy the process was.
As for compositing, I have exported EXR sequence with a number of passes, using Eevee render. Additionally, I have exported extra Freestyle pass, that let’s you add outlines and cartoon-like drawings on top of your render. It was great way to add micro-contrast and details in the relatively simple scene.
I used multi pass export method, to fine tune colours, shadows and blend contrast to my liking in the final video. Additionally, I have replaced simple grey “floor” with a white looped texture I have made earlier, to match the rest of the video.
