killing arnold in linux

sometimes arnold will freeze on you in houdini...
In Linux, open up a new terminal and type -

and maybe, just maybe you'll be able to get Houdini to respond again.

 killall hick-bin will also work

 

pkill hick

 

random spin to particles/packed rigid bodies

stolen from a Toadstorm reply somewhere...

axis might be more finessed than just setting to z as shown.. Same goes for the angle, which I've brute forced to -90 times. Anyway, this will give a bit of spin to your packed rigid bodies

vector axis = set(0,0,1); // the random axis attribute you created

float angle = -90*fit01(rand(@ptnum), -1, 1); // change this to whatever range, in radians

vector4 q = quaternion(angle, axis);

v@w = qconvert(q);
