Bad Collision Model Error

I am making a bunch of random models for the fun of it. I did everything right and read like 5 or 6 tuts on everything that I have done. I made a collision model for a chair, and set all the faces to one smoothing group and everything. But when I try to compile the model in GUIStudioMDL, I keep getting these 3 errors:


g_path:  "deskchair"
Working on "deskchair.qc"
SMD MODEL deskchair.smd
SMD MODEL deskchaircol.smd
WARNING: Bad collision model, check your smoothing groups!!!
WARNING: Truncating model!!!!
WARNING: deskchaircol.smd has bad smoothing groups
Model has 1 convex sub-parts
Collision model completed.

Please help me! I did everything right!

Here is my qc:

$modelname “furniture\deskchair.mdl”
$scale 1
$cdmaterials “models\furniture\deskchair”
$body “Body” “deskchair.smd”
$staticprop
$sequence “Idle” “deskchair.smd” fps 30 ACT_IDLE 1
$keyvalues {
“prop_data” {
“base” “wooden.medium”
}
}
$collisionmodel “deskchaircol.smd” {
$concave
$mass 10.0
$inertia 1.50
$damping 0.00
$rotdamping 0.00
}

Well for starters fix these
WARNING: Bad collision model, check your smoothing groups!!!
WARNING: Truncating model!!!
WARNING: deskchaircol.smd has bad smoothing groups

I fixed it ;). Every single time I post a problem, I fix it like 5 mins later. Please close or do not reply.

how did you fix it please?

What I am about to tell you is only the knowledge of the modeling program I use which is 3ds Max.
When you make your collision model, change the model to Editable Poly. Then, go into face select mode. Press Ctrl+A and select all of the faces. Now in the properties of the faces, you should see Smoothing groups. Go down and hit Clear Smooth or something like that. Then, with all of the faces selected, hit 1 in the smoothing groups. Then export the collision model and you should have it finished!
