How do I break one object into several thousand?

I have this model and want to make it crumple, with physics, into a heap of blocks. It’s currently one object.

What’s the best way to do this?

I figured this part out, but when I go to physics it explodes. What settings do I use?

i dont know the best way, but i would try applying rigid body physics, convex hull collision bounds and then go into edit mode, press a to select all, p -> seperate loose parts.

oh and, if you get it to work, tell me, i want to see it fall :slight_smile: lol

… Yeah, I tried that already…
It explodes.

Edit:
I tweaked it a bit, works now. Thanks.
