Flowing water

Flowing Water

1. Use GCFScape to extract "root\cstrike\materials\models\props\CS_militia\river01.vtf" from "counter-strike source shared.gcf"
2. Create a .VMT file called "flow" and paste the following inside it:

UnLitGeneric
{
	"$basetexture"	"river01"
	"$translucent"	"1"
	"$nocull"	"1"
    	"$decal" 1






	"Proxies"

	{

		"TextureScroll"
		{
			"texturescrollvar" "$baseTextureTransform"
		
			"texturescrollrate" .15
			
			"texturescrollangle" 270.00
		}

	}
	
}

1. Place both of these files in your "<game>/materials" directory and then restart Hammer and/or the SourceSDK.
2. Create your water geometry and give it a nice water texture.
3. Copy all of your water geometry and place this copy one unit above and away from the original geometry.
4. Texture the surface of this new geometry in the new "flow" material.
5. Adjust the scale and shift to conform with the edges of the water.
6. Compile.

Troubleshooting and Notes

• To distribute a map using this method you must include the "river01.vtf" and "flow.vmt" files in the BSP using a program such as BSPzip.
• If the water appears to be flowing the wrong way, or upstream, set the texture's rotation to 180.
• For extra realism particle, splash and sound effects will be required.
