Hi,
I'm making some Asteroid generator and I need to non-uniform scale those object before the copytopoints node (in order to get different Asteroids measures), also I want to be able to change the size of the sphere that creates the erosion of the Asteroids (sphere2).
I did it with Python expresions, but seems to be very slow.
Thanks in advance.

Try the Attribute Randomize SOP?
Or in a Point Wrangle:
Or in a Point Wrangle:
float min = 0.1;
float max = 1.0;
f@pscale = fit01(rand(@ptnum), min, max);

Does it works with non-uniform scales? If I'm not wrong that's only a float.
I also tried with the attribrandomize but it doesn't work with any of the values such as height(from mountain node), sx/sy/sz from the trasnform node or the freq (frequency from the sphere node). Thos nodes are conected before the attribrandomize node.
The thing that I want to do is:
newNode = hou.node('/obj/Asteroid_Maker/sphere1')
transformNode = hou.node('/obj/Asteroid_Maker/transform2')
parm = newNode.parm('scale')
parmSx = transformNode.parm('sx')
parmSy = transformNode.parm('sy')
parmSz = transformNode.parm('sz')
parm.set(random.random() * 7)
parmSx.set(random.random() * 3)
parmSy.set(random.random() * 3)
parmSz.set(random.random() * 3)
But with nodes.
Thanks.
