Bad water textures

When i wanna make some water in my Garry’s mod map ( i get this kind of shit

what i need to do.

I spended more than 2 hours to search without any success .
I use water.lod.controll Please help me!!!

I don’t understand the problem? The underwater effect doesn’t show up in hammer. Also we have 2 question mega threads.

Nodraw every side except the surface.

The flashing is caused by z-fighting…when two planes of differing textures are on the same level. As oskutin said, nodraw all sides of the brush and only texture the top face with water.
