Karineq, I tried the link. I seen that web page before, just could not get the light to work properly with the sun rays. Can anyone tell me how to get those sun rays? I tried the robinwood link, but just could not get it right, maybe I just miss a step or something, but the rays just wont show up. This is what I have in the picture above. (the second one). I have a big light on the top. Below the light is a 2d sheet with a transparent picture that shows on the bottom of the ocean floor. Then all the seaweed and fish. The light is set at Intensity 130, Softness 20 cast shadow is on, infinite light and use gel. The light gel is almost the same picture as the 2d sheet below it, but with a small difference (maybe a little more blurry). Is what I am doing right? If it is, where and how can I get the sun rays to get thru the water? Do I remove the 2d sheet and lower the light, or what I have to do? Thank you...
