Water reflection on surfaces

I just tried several attempts to create that effect but VRAY seems to have some limitations (or my knowledge is limited). I tried putting a spot under the water. Then on top of the water. Then a PNG texture of water ripples (to allow light to pass through) and a spot under that…none would cast the ripple shadow/reflection on the surface. So I gave up and did it in 2 mins in Photoshop. Not 100% accurate but may work in a pinch: [29%20AM] [34%20AM] [40%20AM] [54%20AM]
