Attachments are parented to a joints, and are defined by an offset and a rotation. In game they can be used for particle emission, and item attachment points among other uses. Attachments are stored in an attachment list, and can have multiple parents (influences).

Display

  • To toggle attachment display go Display > Attachments.
  • To toggle attachment name display go to Display >Attachment Names.

Create

  • Right click on a joint item in the outliner, and select Add Attachment.
  • Use the Model > Attachments menu items.

Edit

  • When an attachment is selected via the viewport or an outliner item the gizmo becomes available. Use the gizmo to translate and rotate the attachment.
  • When selected the editable properties of an attachment are accessible via the property editor.

Data Structures

The vmdl attachment data looks like this:

CVattachmentListReference[] m_pAttachmentLists = 
[
	CVattachmentListReference
	{
		CVattachmentList* m_pObject = &CVattachmentList_0
		string m_sFileName = ""
	}
]

m_pAttachmentLists

A list of CVattachmentListReference elements

CVattachmentListReference

A reference to an internal or external CVattachmentList:

Attribute Friendly Name Description Type Default Value
m_pObject pointer to the internal CVattachmentList CVattachmentList*
m_sFileName content relative path to the external CVattachmentList string

A CVattachmentList set list looks like this:

CVattachmentList CVattachmentList_0
{
	string m_name = ""
	CVattachment[] m_attachments = 
	[
		CVattachment
		{
			string m_name = "test"
			CVattachmentInfluence[] m_influences = 
			[
				CVattachmentInfluence
				{
					string m_influenceName = "spine1"
					float(3) m_vTranslationOffset = ( 0.000000, 0.000000, 0.000000 )
					float(3) m_vRotationOffset = ( 0.000000, 0.000000, 0.000000 )
					float m_flWeight = 1.000000
					bool m_bRoot = false
				}
			]
		}
	]
}

CVattachmentList

Attribute Friendly Name Description Type Default Value
m_name Name The name of the attachment list string
m_attachments Attachments List of CVattachment elements CVattachment[]
Note:When it is made external, a CVattachmentList is saved as a ".attach" file.

CVattachment

The data description of the attachment

Attribute Friendly Name Description Type Default Value
m_name Name The name of the attachment list string
m_influences Influences List of CVattachmentInfluence elements CVattachmentInfluence[]

CVattachmentInfluence

The data description of the influence

Attribute Friendly Name Description Type Default Value
m_influenceName Influence Name The name of the influence string
m_vTranslationOffset Translation Translation offset from the influnce float(3) ( 0.000000, 0.000000, 0.000000 )
m_vRotationOffset Rotation Rotation offset from the influnce float(3) ( 0.000000, 0.000000, 0.000000 )
m_flWeight Weight Weight of the influence float 1.0
m_bRoot Is Root Is the root of the model bool true
Note:Changing the influence weight only matters if there are more than one influence.
Tip:Use "Is Root" when adding an attachment to a model that has not joints.
