How to make a prop in XSI for HL2 tutorial - Half-Life 2

In this tutorial I will teach you the most basic way to create a prop in XSI Mod Tool 7.5,
also I'll add a simple texture to it without any bump maps / normal maps / spec maps...
And also show how to export it, create a decent .QC file and a idle.smd file and compile it to be used in HL2. This will all be over video, so pay attention!

Programs needed:
- XSI Mod Tool 6/7.5
- StudioCompiler
- Source SDK - Download through Steam Tools section!
- Valve Plugin for XSI

Optional programs:

- GCFScape 1.8.4

Scripts:

My .QC File

$cd "D:\HL2DM WEPS\prop"

$model "body" "ref.smd"

$cdmaterials "models\props\"
$hboxset "default"
$hbox 0 "square" -3.497  -5.422  -0.013  3.506  5.429  11.584
$surfaceprop "item"
$keyvalues  { prop_data { "base" "Item.Small"  } } 
$illumposition 0.004 0.003 5.785
$sequence idle "idle" loop fps 5.00

$collisionmodel "ref_phy.smd"
