I am trying to apply a water shader to a certain tile in my tileset, but I want the animation to move across all connected tiles, and not simply play an identical animation on every tile.
To do this I would like the animation to vary over the entire 2D space rather than only vary on the UV space within each tile.
I have tried to use FRAGCOORD, however this seems to track the camera/viewport, rather than respect global coordinates. I've also tried POINT_COORD but this seems to return 0 every time.
Forgive me, I am very new to Godot
