all the custom models i have tried. Ok, heres the QC:
$modelname "test/box.mdl"
$model "Body" "test.smd"
$cdmaterials "models/test/"
$hboxset "default"
$surfaceprop "metalpanel"
$sequence idle "test_idle" fps 30.00
$collisionmodel "test_collision.smd" {
$concave
$mass 9.0
$inertia 1.00
$damping 0.00
$rotdamping 0.00
}
the collision model variables are just from a model i decompiled for an example.
Still havnt worked out how to zoom in model viewer!
