Can you move a special effect? Any extra tricks?

can special effects be moved?

are there any custom scripts that exist that allow us to do more with special effects than the 3 that gui offers?

No.

There is a "trick" I guess though.
If you attach a special effect to a dummy unit's origin, you can move the unit and the effect will move with it.

I went ahead and attached the attachable dummy.
Just attach to the dummy unit with that model's origin and all you will see if the FX you attached.
Credits to Vex for the model.

thx a lot!
