So, I'm pretty much done completing my hat - the only thing missing is a jigglebone I want to include. I followed SgtR007's tutorial https://www.youtube.com/watch?v=JP9ce_ygeSA down to a tee more than a few times. Everything goes great until I get to the 6:44 mark... At this part, I would open up Source SKD itemtest to compile everything, then open the .qc file, but it looks so much different.
Here is the exact process I go through:

Once finished with my model, I export it as an SMD.
After that I export two more LODs to the same folder.
Then I launch Source SDK, then go to itemtest, put in my LODs and .TGA then compile
Once compiling is done I go to "Explore MDL Content Dir"
Then I open my .qc with notepad++

Then I put in the Jiggblebone code, save, and compile the .qc with GUIStudioMDL. This is the result:


//
// TODO: parts/dmx ?
// TODO: $surfaceprop is hardcoded
// TODO: Is .mdl extension required?
//

$upaxis Y
$surfaceprop "metal"
$modelname "player/items/soldier/0x05df7880/jigglebonetest/JiggleBonetest.mdl"
//
// TODO: Can fps 30 be removed?
//


$body body "JiggleBonetest.dmx"
$sequence idle "JiggleBonetest.dmx" fps 30

$collisionmodel "JiggleBonetest.dmx" {
$automass
}

//
// TODO: FIXME, switchvalue is just LOD * 6
// 2959 : itemtest.cpp
//

$lod 6
{
replacemodel "JiggleBonetest.dmx" "JiggleBonetest_lod1.dmx"
}

//
// TODO: FIXME, switchvalue is just LOD * 6
// 2959 : itemtest.cpp
//

$lod 12
{
replacemodel "JiggleBonetest.dmx" "JiggleBonetest_lod2.dmx"
}
$jigglebone "jiggle_1" {
is_flexible {
yaw_stiffness 100
yaw_damping 5
pitch_stiffness 100
pitch_damping 5
tip_mass 20
length 20
angle_constraint 90 }
}

Upon launching HLMV and even TF2 after compiling, I see no movement in my hat whatsoever. I have no idea what I'm doing wrong. I've tried Googling the answer, but I can't find anything helpful. Sorry if this topic has been addressed before, but I am totally lost on this one.
