Hellow

I'm new to houdini and was hoping that someone could help me out with this project.

project: have an object break and the peacies will create a new object

ex. drop a box then it breaks and its peices will form a hixagon

1.have an object drop and spilte into 4 peices
2.each piece will go in differnt direction forming new bject as they go
(the formation of the new object should be like the carve node or trim path in after effects)

This is not the most clear question but from what I glean I'd say:
Based on your simple box example, you'll need to pre-model the hexagon, and break it up into pieces that can reform into a cube shape. Assemble the cube from these pieces. Then the rest is hand animation, assuming this is all pre-rendered. You could probably glue the pieces together into the cube, let it drop and break the glue constraints via RBD physics then switch over to key-framed animation to reform the hexagon.
