Q Light Controller+

Hello,
is there a way to live change the heigth/width or the relative position of an EFX using a VC fader?
E.g. I want to have an "8" figure starting very little and becoming wider
thanks

Do you use the search function in the forum?

Through the use of loopback channels you can. There are quit some discussions led about this.
In a loopback universe you create a dimmer. The slider in VC in level mode to that dimmer. The loopback dimmer bound to the width (height) parameter of the EFX.
