does your vmt contain this info?...if not, you will not see blood on weapon.

$detail "models/infected/hunter/hunter_01_detail.vtf"
$detailscale "1.75"
$detailblendfactor .001
$detailblendmode 0
$detailAmount 0
Proxies
{
BloodyHands
{
resultVar $detailAmount
}
Equals
{
srcVar1 $detailAmount
resultVar $detailblendfactor
}
}
}

my vtm containing this text

VertexLitGeneric
{
$baseTexture "models\weapons\melee/katana"
$bumpmap "models\weapons\melee/katana_normal"
$phong 1
$phongboost 3
$phongexponent 30
//$phongtint "[.85 .85 1]"
$phongfresnelranges "[1 5 10]"
//$color2 "[1.5 1.5 1.5]"
$envmap env_cubemap
$envmaptint "[0.02 0.02 0.02]"
//$envmaptint "[0.3 0.3 0.3]"
//$envmapFresnelMinMaxExp "[0 .5 .4]"
//$envmapfresnel 1
$phongalbedotint 1
