Blender prop collision error!

[Consilio]

So, I have created a doorframe along with the collision mesh. However, when I compile it through Crowbar the doorframe turns into a single solid box (which doesn't allow me to walk through it ingame). I have had so much trouble trying to figure this out by googling so many topics on this. This is my last resort. I am so desperate, help!

Make sure you have this line in your qc file near physics:

$maxconvexpieces 3 (this tells crowbar that it will define 3 parts instead of one)

The reason why it does that is because it is optimizing the collisions so that the game can run better. I've bumped into it too, but I got it to work for a chair.

That didn't seem to work :/ This is my qc file:

$modelname "cwhallsupport_addon\hallsupport\cwhallsupport.mdl"

$scale 1

$body 1 "cwhallsupport.smd"

$cdmaterials "hallsupport\cwhallsupport\"

$surfaceprop "metal"

$contents "solid"

$sequence "idle" "anims\cwhallsupport_idle.smd" {
fps 1
}

$collisionmodel "cwhallsupport_phys.smd"
{
$automass
$inertia 1
$damping 0
$rotdamping 0
$concave
}

You need to add it under the $collisionmodel for it to work.
My chair for example:

$collisionmodel "jlor_chair_gaming_physics.smd"
{
$mass 15
$inertia 1
$damping 0
$rotdamping 0
$rootbone "static_prop"
$concave
--> $maxconvexpieces 7

}

Don't forget to specify how many parts your collision model have. Make sure your physics model are separate parts, or else the mesh would merge as one for some weird reason.

I have four separate boxes that make out the frame but when I seperate them from being one model, only one of the boxes gets exported instead of all four?

[lorjason34]

That's because the boxes are all independent entities. Separate them, but then have them joined by selecting all of them, and press ctrl+j. Then go to edit, and press l on one of them. That's what I mean.

Like this gaming chair physics, it's one, but has multiple separate vertices.

[Consilio]

After joining them, I entered edit mode but I wasnt able to select anything (other than the vertices/corners)

Switch to face mode for that. Since I've seen the picture, I can assume you can retry what you did previously, and use the $maxconvexpieces command under the collison model. Make sure you specify how many parts there are.

Didn't work :/ Sorry, I'm not trying to be difficult - I have been trying to figure this out for awhile. Here's the file for the collision mesh. Maybe you can see where I went wrong.

Also, heres a screenshot of my crowbar before I compile: https://imgur.com/a/GJjsuNO

That's helpful. I will see if I can get it to work on my side.

I got it to work. Only problem for me was the physics model turns 90 degrees to the right every time I compile, so I rotated it 90 degrees to the other direction.
I think it's something to do with the qc file and the parenting of the collision model. I set up the collision line like this:
$collisionmodel "cwhallsupport_phys.smd"
{
$mass 15
$inertia 1
$damping 0
$rotdamping 0
$rootbone "static_prop"
$concave
$maxconvexpieces 4

}
I don't know what else will fix it, but add that whole line to your qc file and it should work.

I have replaced the coding to what you have suppiled but still no success. I am so sorry for wasting your day. I would understand if you'd prefer to stop here.

Nevermind, I have done it!
