Im trying to use the WarpMask effect on a tiled "grass" background, but i'm only getting a white background.
Am I doing something wrong? this is my first time using effects. Do I have to enable something somewhere else?
What i'm expecting from the effect description is an animated wave distorition of the grass, giving a wind-like effect over the grass.
But as I said, I'm only getting a white background. If I disable the effect, the tiled grass looks fine again.
Please help :)
