Did some more experimentation with the fly eye lenticular effect which can be tilted sideways as well as up and downward
I used 9 pictures in a 3x3 grid. I made the grid by using two RGB ramps with no interpolation, one in U direction and the other one in V direction and multiplied the different channels together to get a grid in which tile has an individual color (or picture in this case).
For the lenses I used a circular ramp as displacement map.
Does anybody know an easier way how to create a procedural grid with individual tiles which also could be larger than 3x3 to get a smoother transition for the animation? With my method it's becoming pretty messy creating a 5x5 grid or bigger...
