first thing, shader work actually? (ie it "behave" like water in game 
). If yes You need to add different blendfunc.
this is and shader from urt:

Shader works. It is water, but it is not transparent.
Code: Select all
textures/greatwall/greatwall_water
{
qer_editorimage textures/greatwall/greatwall_water.tga
qer_trans 0.2
surfaceparm alphashadow
surfaceparm lightfilter
surfaceparm nomarks
surfaceparm nonsolid
surfaceparm trans
surfaceparm water
cull disable
{
map textures/greatwall/greatwall_water.tga
blendfunc GL_SRC_ALPHA GL_ONE_MINUS_SRC_ALPHA
tcMod turb 0.0 0.1 1.0 0.1
tcmod scroll 0.01 0.01
}
{
map $lightmap
blendfunc filter
}

No alpha channel that I'm aware of. I'll try that blendfunc.

blendfunc GL_SRC_ALPHA GL_ONE_MINUS_SRC_ALPHA blends the alpha channel with white pixels being opaque and black being fully transparent. if no alpha channel is present. no blend 
either add an alpha channel or experiment with different blends, you could also try my favourite
blendfunc blend
alphaGen const 0.2

How do I add an alpha channel? I use GIMP 2.4 for all texturing I do.

I got alpha channels to work but my water is still not transparent. I even tried to copy a working example (from ut4_edo_b1) and it still doesn't work. I'm out of ideas...
