I would have thought with almost 1000 views someone would say "hey yeah I'm also having a problem loading the scene too, or not"
My Houdini install could have an issue or perhaps yours, either way would have been helpful to know huh.


Glad you got it solved

A very quick and dirty way to achieve this, no Japanese required.

Drop a solver sop "inside" your RBD Bullet Solver connected to either pre or post solve, didn't notice
much difference in this case tbh, then add an attribute wrangle inside the solver.

v@v.z = 0; will resist/stop Z axis velocity movement

v@w.z = 0; same thing for rotation

Here is an example how to use Kinefx rig to unfold a box.....you should be able to apply this to your scene
with little effort.

Basic principle:

Break the box into parts, pack those parts and use capture pack geo to move each part
using a basic skeleton rig, then unpack if required.....ideal for rigging solid parts that are not
required to deform, like a robot arm for example.....use the rigpose node to animate the rig.


Hope this helps.
