Portal 2: Infinite Loop (Blender Animation)

I've always wanted to create a looping animation, and also something in the world of Portal. So why not make a looping animation set in the world from the game Portal 2.

I already had a scene I created back in 2016, but I wanted to take it to the next level.

The environment was made in blender (rendered with cycles), and the portals were created using After effects.
