These five screencaps will show Blender users how to make their images or renders look pixelated, like old video game sprites, and, then, how to animate that pixelization effect. The challenge of animating them was solved very quickly by Olson, of GetBlended.org, in mere minutes.
Making a still image pixelized in Blender is very easy, requiring only three Nodes in the compositor. What they do is first shrink the image down to a tiny size, and then just re-inflate it. The Node in the middle, “Pixelated”, is necessary because, without it, Blender seems to nullify the first node where it is shrunk down:
Now, though, let’s say that you want to animate that effect, so that it goes from pixelated to high-resolution. Superficially, this would seem very easy: Just take the two Scale values from our Transform Nodes above, and then animate them. But, this is where I ran into a problem…
The reason that this weird problem occurs is because of the difference in the ranges between the two Scale values, as shown here:
But no worries! I explained my problem to Olson of GetBlended.org, and he quickly used his sharp Englishman’s mind to create a solution…[See following post.]
