$definebone

$definebone (name) (parent) (X) (Y) (Z) (xr) (yr) (zr) (fixup XR) (fixup YR) (fixup ZR)

• Defines a bone outside of any .smd source. This is useful when building animation only mdl’s that would otherwise optimize out all the bones since none of them are connected to any geometry or attachment points. You can get studiomdl to dump this out using the "-definebones" command line option.
