Rigidbody to fall in precise end goal

[zjie]

Hi all, I wanted to do a rigidbody simulation where the rigidbodies body start with random orientation, they falls and line up in neat and orderly manner, but I just couldn't wrap my head around it, is there a way to do it? 

I don't want to do a reverse simulation as it will looks fake.

Thanks!

you can set a goal position, to reference the END position to be the one you are aiming for, but i don't think this will look any less fake than simulating it backward

By goal position, do you mean using a popattract? I'm new to Houdini and as far as I have noticed, the thing about popattract is that the points will hover around the goal, instead of sticking onto them.

So now I have this setup, is there a way to set it up that once the rigidbody hit the floor, it will "blend" to the rest position in the next 20 frames?

Yea so what I wanted to achieve is, for each piece, once they hit the collision plane, they will blend to the resting position, is there a way to do it? Anyone have any clue?

I think this video can give you direction. This in Russian though... but all the actions are on the screen.
