I have made some research and still can´t find the answer.

I´m trying to give some rotation to each of this particles in this little example.

I have try with torque but i didn´t work, i have seen something of VEX but still dont understand that.

Please someone who can help me.

Thanks

You can add a custom attribute for define rotation for each point.

Attribute Name : rot
Class : Point
Type : Float
Size : 4

then define your rotation direction with X , Y , Z component and define Angle(in Radian) with W component.
