I am confident in saying that this, as of May 20, 2022, is the single most realistic animated short film ever made. Period. It is simply stunning how real it looks. Thinking about the amount of work this must have taken makes my head hurt. The water, reflections, foliage, physics, EVERYTHING, looks real. A bunch of people won't appreciate the achievement this is because its... different. Its strange and beautiful and its a monument to how far technology has come. There is a lot that can make you think, "Oh, this is fake," without you even realizing it. You'll see a weird texture or something won't fall the right way or light won't be reflected correctly, and that is all it takes to make you realize what you are seeing is computer generated, so in order for you to perceive something as real, EVERYTHING has to work, there can be no mistakes. This is as close to perfect (it is not perfect, but WOW is it close) in this regard as we've gotten so far. This is as close as we've ever come to bridging the uncanny valley...
I wonder how long it took to render :)
