This effect is so close to being perfect for my needs.
The "DriftAmount" property appears to translate the effect across the X axis which is exactly what I need for my project. But is there any way to manipulate the effect accross the Y axis in the same manner?
If that's possible, or if it could be added, this effect would be absolutely perfect for my project.

I'm trying to use this effect to get an infinitely scrolling starfield with a parallax-like effect without having to rely on the inbuilt layer parallax in C3 or using any other weird workarounds.

I still get an error when trying to launch the game;
