Gmod 13 texture help

I am trying to make a prop into gmod but only one problem my model works fine but the texture won’t show up I put it in its matching folder and nothing I put the qc file in the right place under user hl2 folder and garrysmod gameinfo orangebox under guis studio this is the code that was used.

$cd “C:\Users\User\Desktop\model”
$modelname “cube.mdl”
$model “studio” “ref.smd”
$cdmaterials “materials\models\cube”

$hboxset “default”
$surfaceprop “metal”
$keyvalues { prop_data { “base” “metal.Small” } }
$sequence idle “seq.smd” fps 1.00
$collisionmodel “phys.smd” {
$concave
$mass 0.2
$inertia 1.00
$damping 0.00
$rotdamping 0.00
}

The $cdmaterials command automatically recognizes the materials folder as the starting path. You don’t have to put it there or in the VMT. Unless of course your texture is in materials/materials/models/cube/

Then what am I suppose to do,I mean how do you think I should make this qc?

$cdmaterials “models\cube”

Still the same problem I don’t know if its because I used common/Garrysmod folder of where I placed the models,but heres what it looks now

$cd “C:\Users\user\Desktop\model”
$modelname “cube.mdl”
$model “studio” “ref.smd”
$cdmaterials “models\cube”

$hboxset “default”
$surfaceprop “metal”
$keyvalues { prop_data { “base” “metal.Small” } }
$sequence idle “seq.smd” fps 1.00
$collisionmodel “phys.smd” {
$concave
$mass 0.2
$inertia 1.00
$damping 0.00
$rotdamping 0.00
}
