Model not showing up ingame

[theholygod]

So, i've compiled a few different types of models so far, and if something goes wrong i can usually fix it with trial and error.

Now i am completely stuck with a model i have recently tried to compile, this is the QC:

$cd "C:\Documents and Settings\Chris\Desktop\neoforts\jetpack"
$modelname "jetpack.mdl"
$model "Body" "jetpacknew.smd"
$cdmaterials "models\jetpack\"


$surfaceprop "metal_small"
$sequence Idle "Idle" ACT_IDLE 1 fps 30.00
$collisionmodel "phymodelnew.smd" {

	$concave
	$mass 10.0
	$inertia 1.00
	$damping 0.00
	$rotdamping 0.00
}

The model compiles fine, no errors or anything. It shows up as it should in HL2 Model Viewer and shows up in Hammer when used as a prop_static or prop_physics, but just isnt there ingame.

I've had a similar problem before where the model is invisible, but i was able to "feel" the collision model. This isnt the same case.

Does anyone know how i can fix this?

How do you resolve the invisible models problem. Because iv been getting that when i ported css models into hl2 (for my own personal use) I can see the collision model in hammers model view though is it something to do with vmt's?. Any ideas?
