Before I start designing it I wanted to check if there could be alternative ways of creating this.
Water is going to have some opacity, and I would like a Barrel to float in the water, and the part "below" the water should be a different color (Probably "Blueish").
That would be 3D stuff of course, and currently I can only think of creating an animation of a barrel that is already colored as if under-water.
But any other ideas on this :) ?
