Rendering part of an image onto an object

Say I have 4 puzzle pieces of irregular shapes, that all fit together into a square shape. I also have a square shaped image. Can someone push me in right direction as to how to render the pieces with the corresponding pieces of the image?

I’m not even sure of the terminology to ask for hep with.

You would UV map the pieces. The easiest thing would be to UV map the square first before breaking it into separate objects.

Eric5h5’s got it right.

While something like this could be done in Unity with custom code or something like ProBuilder, it’s probably easiest to just use a dedicated 3D modeling program like Blender to do the work.
