$attachment

GoldSrc

Source Engine

$attachment is a QC command available in all  Source games. It defines attachments 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 and Compiling a model.

Syntax

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

The optional commands are:

absolute

Parented to the model's origin. The offset is still relative to the given parent bone, however!

rigid

Declares that the bone this attachment is parented to will not move, allowing Studiomdl to delete that bone. The attachment will be re-parented to the next bone in the hierarchy. Useful for precise attachment placement without keeping useless bones.

rotate

Rotates the attachment, in degrees, relative to its parent bone / the origin.

Todo: There is some weirdness in how the value is interpreted by Studiomdl.

world_align

Flags the attachment to align with the world instead of its own root.

Todo: This need more testing.

x_and_z_axes

Similar to rotate but only the Y axis stays at its default value.

Todo: Needs testing. Why does this exist? looks useless

Examples

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
