Howto make water less transparent & highlite

[Bikerdude]

So got the following std water material def -

extures/water_source/water_green_nontransparent
{
    qer_editorimage textures/water_source/water_green
    discrete
    nonsolid
    water
    twosided
    noselfshadow
    noshadows

    diffusemap    textures/water_source/water_green
    {
        blend bumpmap
        map    textures/water_source/water_green_local
        translate     0.01 * sintable[time * ((( parm5 + 0.1) - (( parm5 || 0) * 0.1)) * 0.8)], 0.01 * sintable[time * (( parm5 + 0.1) - (( parm5 || 0) * 0.1))]
        scale 0.5,0.5
    }
    {
        vertexProgram HeatHazeWithMaskAndDepth.vfp
        // 0.1 * 0.4 => 0.04
        vertexParm 0 time * ((( parm5 + 0.1) - (( parm5 || 0) * 0.1)) * 0.4), time * ((( parm5 + 0.1) - (( parm5 || 0) * 0.1)) * 2)
        vertexParm 1 (( parm6 + 1.5) - (( parm6 || 0) * 1.5))
        fragmentProgram HeatHazeWithMaskAndDepth.vfp
        fragmentMap 0 _currentRender
        fragmentMap 1 textures/sfx/vp1
        fragmentMap 2 textures/water_source/vp_water
        fragmentMap 3 _currentDepth
    }
}

How do I make is less transparent and not lighten textures under the water level -

 

 

[Dragofer]

One way is to put a dark foglight into the water. Although there might be other ways?

[Bikerdude]

I really want to fix the material shader than that fudge it by adding another entity...

 

im guessing? the highlighted textures under the water line are the result of some blending..?

You have to change the shader program to get the desired effect.

You'll need to use a filtering blend I think. Right now the colour representing the light coming off the water is being added to the colour of the light reflected by the background, so the overall result is brighter than either.

 

If you make your diffuse map a blend of any kind, it'll stop using the bumpmap so that's no good.

 

You could tone down the background by using an extra material stage as the filtering blend, exactly like putting a thin sheet of dark glass just under the water surface:

 

 

textures/water_source/water_green_nontransparent
{
    qer_editorimage textures/water_source/water_green
    discrete
    nonsolid
    water
    twosided
    noselfshadow
    noshadows
    
    // Try to darken the background
    {
        blend filter
        map _white
        rgb 0.5         // 0.0 means fully black. 1.0 won't darken at all
    }
    diffusemap    textures/water_source/water_green
    {
        blend bumpmap
        map    textures/water_source/water_green_local
        translate     0.01 * sintable[time * ((( parm5 + 0.1) - (( parm5 || 0) * 0.1)) * 0.8)], 0.01 * sintable[time * (( parm5 + 0.1) - (( parm5 || 0) * 0.1))]
        scale 0.5,0.5
    }
    {
        vertexProgram HeatHazeWithMaskAndDepth.vfp
        // 0.1 * 0.4 => 0.04
        vertexParm 0 time * ((( parm5 + 0.1) - (( parm5 || 0) * 0.1)) * 0.4), time * ((( parm5 + 0.1) - (( parm5 || 0) * 0.1)) * 2)
        vertexParm 1 (( parm6 + 1.5) - (( parm6 || 0) * 1.5))
        fragmentProgram HeatHazeWithMaskAndDepth.vfp
        fragmentMap 0 _currentRender
        fragmentMap 1 textures/sfx/vp1
        fragmentMap 2 textures/water_source/vp_water
        fragmentMap 3 _currentDepth
    }
}

 

 

Without testing, I'm not sure whether that'll darken just the background, or the water surface too. I think it'll be just the background, but on second thoughts darkening the water too might look best. To do that you'd move the new stage to after the diffusemap and bumpmap. The idea now is it's only meant to darken the background so it gets listed and drawn first, before the water gets drawn on top. If you move it last, it'll darken the background and the surface.

You can adjust the amount of darkening by changing the rgb 0.5 to any value between 0 (background fully black) to 1 (no darkening at all, like the current shader)

Nice, thanks fella.

 

Will give that a go this evening!
