Water shader won't let the light pass

Hi,
The daytime water shader and Nighttime water shader are the same and my problem is the same for both.
Even if I uncheck the receive shadow box of the object that this shader is assigned to,lights wont go through it.
Here is the screenshot:

Mention that I have no problem with Water4 example which is good for ocean.

System spec:
GTX 580 with latest WHQL driver.
I7-2600K
16GB ram
Win 7 64-bit ultimate

Is ZWrite Off?

I opened the shader and saw nothing about the ZWrite which means on as default,anyway I added “ZWrite On” under the Pass and still nothing changes.

I meant it should be Off :stuck_out_tongue:

I suspect On is what’s causing the issue.

Even when it is ZWrite Off no changes will happen but I understood that this shader is working with Directional lights very well.
