Under water lighting (Pool)

I’m trying to add lighting to a swimming pool. I have a directional light inside the pool with high intensity and using “OceanPlanes” for my water. But I can’t get the ligtht to show up above the water surface. The light is clearly showing up on the pool walls but not in the water.

The first image is what I’m trying to achieve. What am I missing to get that kind of light distribution?

Any suggestions?

try this steps maybe it resolved :
1- lighting need to build in your last image
2- if its not static light , try to change it to movable light
3- change lighting channel in your direct light and pool .
4- disable cast shadow on you water surface
if its not working , make a simple sample of your project and post it here , maybe we can help you.
