Falling Box

[Bernard]

Hello,

I have a DOP simulation with a box falling on a plane.

The box is a RBD Object.

I want the top of this box to flip open when the box hits the ground.

The top of the box may be 1 piece or 4 pieces( like a real box).

How can I do this and is it possible to post an example file?

thanks,

bern

no sample file just an idea:

in sops you propably merge back the dop-sim.

in a switch switch between the sim box and your original box depending on velocity, simstate, dopfield whatever.

this switch condition should also trigger the animation of the opening box ...

Hello,

thanks,

would it also be possible in Houdini DOPs to make the top of the box a RBD Object and constrain it to the rest of the box?

anyway - here is my humble try on this topic.

if vely of the falling is near 0 the particles start to emit.

I changed the dopfield to cumulativeMovement, which is much easier.

A group selects the topmost face ...

I guess in your setup I maybe even need to direct the dop to end in a specific position.
