$attachment is a QC command that defines a location on a model. Attachments are identified by their name, and can be either relative to the model's origin or parented to a bone.

See also Attachments.


$attachment <string|name> <string|parent bone> <Vector|offset> [absolute] [rigid] [rotate <angle|orientation>]

The optional commands are:

Parented to the model's origin. The offset is still relative to the given parent bone, however!
Declares that the bone this attachment is parented to will not move, allowing Studiomdl to optimise it out. Used to convert bones created in a modelling package into attachments.
Rotates the attachment, in degrees, relative to its parent bone / the origin.
To do: There is some weirdness in how the value is interpreted by Studiomdl.


Relative to bone:

$attachment "anim_attachment_RH" "ValveBiped.Anim_Attachment_RH" -0.00 -0.00 0.00 rotate -90.00 -90.00 0.00

Relative to origin (no bone name required):

$attachment "nozzle" "" 0 4.8 0 absolute
