There's no pleasing some people! :-)
Here's a version that only works on clouds (since a point collection doesn't
have rotation data), and includes rotation and scale in the transform. I'm also
grabbing the size from the particle and setting the null size parameter. You
could use the particle size to set the null scale if you want:
function NullsOnCloud(inCloud)
{
if(!inCloud) inCloud = selection(0);
// Get global transform from inCloud
var gTrans = inCloud.kinematics.global.transform;
// Get particle collection from inCloud
var particles = inCloud.ActivePrimitive.particles;
// For each particle, create a null and transform it to the point
var rootNull = ActiveSceneRoot.AddNull('ParticleNulls');
for(var i=0; i<particles.count; i++){
var pTrans = XSIMath.CreateTransform();
// Set local translation from particle
var pos = particles(i).position;
pTrans.SetTranslation(pos);
// Set local rotation from particle
var rot = particles(i).rotation;
pTrans.SetRotationFromXYZAngles(rot);
// Multiply local transform by global trans of cloud
pTrans.MulInPlace(gTrans);
// Create null and set global transform
var node = rootNull.AddNull('particle' + i + 'Null');
node.kinematics.global.transform = pTrans;
// Set the size of the null from the particle size
node.size.value = particles(i).size;
}
}
