[quote="Davioware":6d8rhzq9]I think Ash mentioned that multi pass effects don't work in construct.[/quote:6d8rhzq9]
Yup. That's the reason. And multipass is the way to go, so the only way currently is stacking them.
[quote="Davioware":6d8rhzq9]hopefully someone will implement a value control for blur horizontal and blur vertical eventually.[/quote:6d8rhzq9]
I did, a good while ago O_O It's in the completed plugins forum.
It's called "blur motion" and also has runtime angle control, so the horizontal and vertical fx are the same. Which means it crashes if you stack it four times X_x
I guess you could copy it with another name and use two of each as a workaround.
