Salut Olivier :-)

Particle sketch looks like a freezed cloud. I think you can only change rotation/position with a script ( sorry :-p ). But don't be afraid, you don't need to use event for your needs as it is a "static" operation :-).

So open your script editor and run : 

//change "cloud" to your cloud name !
var oCloud = ActiveSceneRoot.FindChild
("cloud");

for ( var i = 0; i < oCloud.Particles.count
 ; i++ )
{
    var oPart = oCloud.Particles.item(i);
    //For example you want bigger particles if Y>2
    var oIncreaseSize = 2
    if(oPart.position.y>oIncreaseSize)
    {
        NewSize = oPart.position.y*(1/oIncreaseSize);//*Math.random());
        oPart.Size = NewSize;//You can multiply by Math.random() if you want.
        
        var MyRot = XSIMath.CreateVector3();
        MyRot.Set(NewSize,NewSize,NewSize)
        oPart.Rotation = MyRot;
    }
}

It is just an example. I won't forget my mobile phone this afternoon so I will call you ;-)

Hi all,

Making a tree, I've used particles to generate the leaves (Cloud emiting
from tree trunk + instance particles). I'm trying now to add more leaves
here and there using "sketch particles". I can't find a way to vary
(var) the size or the rotation of the particles emited with "sketch
particles".

Is there a simple way ?

Thanks all.
