Water looks invisible

Support Particles and Physics Simulations

Hello!
I’m trying to render my scene from Blender 2.49 in Blender 2.78. Here the video that I have got in 2.49:

I have rebaked water domain, but have the problem:
In the editor of the scene I see the water, but rendered it looks absolutely transparent before ice fall to water (frame 27).
How to make it visible even in the calm?
Thank you.

OK Long, clicking and I have found the problem.
On the water was 2 modifiers:

  1. Fludism
  2. Boolean
    So on the boolean was operation “Difference”, instead of “Union”. And there is was set “NOT display modifier in viewport” and “use modifier during render”. So I have seen water in the viewport without any boolean operation, but on the rendered picture “difference” was nothing.
