Post some details. Usually posting the content of your VMT file helps.

okay.
But I have to warn ya, I got practically no exp with Modelling-Stuff and jsut made this with the help of a friend and got the vmt and qc files from the official- and a com-guide

------------------------------------------

QC-FILE

$modelname "76561198055072290\yourswordname\yourswordname.mdl"
$cdmaterials "models\76561198055072290\yourswordname"
$surfaceprop "metal"
$bonemerge sword_grip
$scale 1.0
$body "Body" "yourswordname_ref.smd"
$sequence idle "yourswordname_ref.smd" loop fps 1.00
$collisionmodel "yourswordname_phy.smd"
{
$mass 1
}

----------------------------------------------

VMT-FILE

"yourswordname"
{
"include" "materials/models/shared/swords.vmt" // import to ensure that common requirements are met, for example the charge effect on swords, player models
"insert"
{
"$basetexture" "models/76561198055072290/yourswordname" //the name of your diffuse vtf
"$bumpmap" "models/76561198055072290/yourswordname_nrm" //the name of your normal map vtf
"$normalmapalphaenvmapmask" "1" //use the alpha channel in your normal map as the specular map.
}
}

vmt files need to be in "models/76561198055072290/yourswordname/"

yea, I got my .vmt-file in my materials/models/steamid/yourswordname & materials/steamid & models/steamid/yourswordname

But it still does complain about the materials/models/steamid/yourswordname/yourswordname.vmt

look at the file path for your basetexture
you need
"$basetexture" "models/76561198055072290/yourswordname/yourswordname"
"$bumpmap" "models/76561198055072290/yourswordname/yourswordname_nrm"

welp, I checked the paths but they seem to be okay...

Sorry I was unclear, I meant the file path inside the vmt file.

what's wrong with them, I think I checked them

you are missing the folder "/yourswordname/" between steam id and texture image name

Did that help?

yea, but now I encountered a problem with the program itself.
It seems like the Y-Axis which should be the lenght of the blade is now replaced with the X-Axis, so when I put the upward-axis on the Y-Axis (I'm not sure which one it was atm) the sword fits, but the blade is gazing into the sky...
