You’ve seen Lenticulars: they’re those images behind finely cogitated perspex - as you look at them from different angles you see different frames of a short animation. This simulates them in Cycles and Eevee.
Press R Z in the 3D view to see the lenticular in action.
This lenticular shader works for a spritesheet which is arranged vertically – for a horizontally arranged sprite-sheet go into the Leticular group and swap the green in the two mix nodes for red. (FF0000)
In the UV editor, position the UV over one of your frames on the spritesheet.
There are two controls on the Lenticular shader group: Frames is how many frames the animation has, and Freq is frequency … how many times the animation will repeat over a 90° rotation.
The raptor (or perhaps jesus lizard) sprite is my own.
Enjoy! And while this is CC0 I would be interested to know if you end up using it for anything.
