The best way I've found for shattering objects is to use Cell Fracture on the model of choice in Blender (there are tutorials so won't get into that part).
Once complreted, export all the pieces as a single object but set it to make objects as groups. -Import it to Poser, first make sure the materials/textures are good, then open the Group Editor. -Click Spawn Props. -From there you can hide or delete the original from the scene.

• I would then use an empty Figure as the parent for all of the pieces. (you could enter Setup w a invisible tiny object, even 1 vert so its invisible, then exit without adding bones)
• Setup a Bullet Physics assigning all of the fractures pieces to Rigid, a floor prop, etc. to choreographed (collision object) and see what happens when you run the sim with default settings, then tweak as needed.

If you really wanna go further you can add a choreographed object to animate (like a ball bursting through) to cause the pieces to react in certain ways. then hide it. I know I skipped a lot of details but this is basically what I've done.

[I'd show a gif but apparently they do not work on this forum.]

Edit: Here's an example
