Creating a smart object in a "puzzle" style

Here is what I was talking about. multible smart objects that if one is changed, all the other ones change. Then each SO as a vector mask of a puzzle piece, so you can move them around. Or you can put them all in another SO and transform them as a group. a layer style of bevel and emboss was given to all the layers.

I'm not sure if this is what you want, but you might want to check out this link with actions.

You can do this with a smart object that you duplicate to the number of puzzles  pieces that you want. There might be a limit on the number of smart objects. Then you need to add a vector mask to each of those smart objects for each puzzle piece. Using Illustrator to create the vector masks would be easier, as you could use the divide command to separate multiple paths into self contained puzzle shapes.

Hi for making anything custome like mockup , you first need to learn how smart objects work check following video of mockup making you will get an idea how you can work on your own project.
