General shaders for your game/map.

Tree leafs:

textures/tree/pine_leaf
{
	surfaceparm alphashadow
	surfaceparm nonsolid
	surfaceparm nomarks
	surfaceparm noimpact
	surfaceparm nolightmap
	nopicmip
	dp_noshadow
	
	cull none
	surfaceparm trans 
	deformVertexes wave 15 sin 0 2 0 .1 //animation
	{
		map textures/tree/pine_leaf
		rgbGen vertex
		depthWrite
		alphaFunc GE128
	}
}

Grass:

textures/grass/grass01
{
	surfaceparm alphashadow
	surfaceparm nonsolid
	surfaceparm nomarks
	surfaceparm noimpact
	surfaceparm nolightmap
	nopicmip
	dp_noshadow
	
	cull disable
	surfaceparm trans 
	deformVertexes wave 15 sin 0 2 0 .1 //animation
	deformVertexes autoSprite //look into camera
	{
		map textures/grass/grass01.tga
		rgbGen vertex
		depthWrite
		alphaFunc GE128
	}
}

Sky:

textures/sky

	surfaceparm noimpact
	surfaceparm nomarks
	surfaceparm nolightmap
	surfaceparm sky
	nopicmip
	nomipmaps
	
	skyparms env/sky - -
}

Decals (trash on the ground):

textures/decal/decal09
{
	surfaceparm trans
	surfaceparm nonsolid
	surfaceparm noimpact
	nopicmip
	dp_noshadow
	
    cull back
    {
        map textures/decal/decal09
        blendFunc GL_SRC_ALPHA GL_ONE_MINUS_SRC_ALPHA
        alphaFunc GT0
        depthWrite
        rgbGen identity
    }
    {
        map $lightmap
        rgbGen identity
        blendFunc GL_DST_COLOR GL_ZERO
        depthFunc equal
    }
}

Fence/grate:

textures/fence/fence01
{
	surfaceparm trans
    surfaceparm metalsteps
	surfaceparm noimpact
	surfaceparm nonsolid
	surfaceparm nomarks
    cull none
	qer_alphaFunc gequal 0.5

    // A GRATE OR GRILL THAT CAN BE SEEN FROM BOTH SIDES
    {
        map textures/fence/fence01
        blendFunc GL_SRC_ALPHA GL_ONE_MINUS_SRC_ALPHA
        alphaFunc GT0
        depthWrite
        rgbGen identity
    }
    {
        map $lightmap
        rgbGen identity
        blendFunc GL_DST_COLOR GL_ZERO
        depthFunc equal
    }
}
