i have this problem that i am trying to solve now. I am building a ornament pool with underwater lights shining out of the water and onto the walls.
I tried using all the settings i can find from tutorials from all over the net but still couldn't achieve a gd render.
Is there a tutorial someone can point me to? I would like to use photometric lights and caustic rendering if possible but i wouldn't mind using generic lights too.
attached is a test render of my scene. I have removed all underwater lights as they simply won't pass throught the water.
