Help with script

[DeletedAccount1111]

Hi, I'm currently using custom cars in my server (loaded with modloader) and i wanted to apply some paintjobs to them, but seems that i cant do that thing. So i want to lnow how I am suposed to do this. At the moment, I'm using a script that i found here: viewtopic.php?f=91&t=35778

And here it is:

The lua:

    addEventHandler( "onClientResourceStart", resourceRoot, 
        function() 
        
            texture = dxCreateTexture ( "uranus2body256.png" ) 
            shader, tec = dxCreateShader( "shader.fx" ) 
            
            --bit of sanity checking 
            if not shader then 
                outputConsole( "Could not create shader. Please use debugscript 3" ) 
                destroyElement( texture ) 
                return 
            elseif not texture then 
                outputConsole( "loading texture failed" ) 
                destroyElement ( shader ) 
                tec = nil 
                return 
            else 
                engineApplyShaderToWorldTexture ( shader, "uranus2body256" ) 
                dxSetShaderValue ( shader, "gTexture", texture ) 
            end 
            
        end 
    ) 

the fx:

    texture gTexture; 
      
    technique TexReplace 
    { 
        pass P0 
        { 
            Texture[0] = gTexture; 
        } 
    } 

and obviously, the meta:

    "Shader - UV Scroll" version="0.0.3" type="script" /> 
    

The car is some AE86 from Emzone guys. (Just if this helps)

If an admin grants me permission, i'll upload the script folder to mediafire or to mega, so you can see what i created.
