Make model work with prop_physics?

[Skype]

Hi guys,

I exported a model and it appears in hammer fine, all dandy, works in-game as a prop_static. But when I change the entity to a prop_physics it just disappears. I had this problem before, but that was with valve's models.

How do I make it so that it works with prop_physics?

My QC file:

// Output .MDL
$modelname "jon/mod_lamp.mdl" 

// Directory of materials that the model uses
$cdmaterials "models/jon" 

// Model properties

// model is a static prop
//$staticprop

// Material properties
$surfaceprop "Metal"

// Scale all units by a factor of 40
$scale 5

// Base or Reference .SMD
$body studio "./mod_lamp" 

// sequences: all sequences are in $cd
$sequence idle "mod_lamp_idle.smd" loop fps 15 

// Physics data
$collisionmodel "mod_lamp_phys.smd" {
$Mass 5
$concave}

I tried removing "$staticprop" but that just gave me a compile error.

i know nothing about modeling, but i'm just gonna go out on a limb here and say add $physicsprop

Fuck yeah I fixed it. Adding

$keyvalues
{
    prop_data
    {
        base    metal.Medium
    }
}

to the QC file made it usable with prop_physics.
