Square wave.

Hello all,
Making a circular wave on a water texture is just by applying a zigzag/twirl/radial blur filter. How do I make a square wave then? Like dropping a plank of wood or something rectangle on to a pond.

Cheers.

make a rectangular selection the click select inverse and try your other method :\

I think if you drop a rectangular thing into a pond, it won't ripple like a square. It will still make a circle.

Thanks guys. It works and tried dipping something rectangle on water, it still a circular wave. How dump I am.

hey its just one of those things people dont think about; dont stress it, i probably would have made a rectangular one too.
