$weightlist

$weightlist is a c0 available in all Source games. It defines the influence to which each bone in a model is affected by a $sequence or $animation. For example, you could set the weight of the leg bones to 0 to only animate the top half of the skeleton.

A $weightlist can be reused as many times as is needed. It must come above anything that uses it in the QC.

Note:No, this has nothing to do with physical weight or mass.

Note:Values above 1 are accepted unlike what one might expect. These will multiply the motion of the animation.

Tip:You can have up to 128 $weightlists commands

Tip:You can declare a default weight list with $defaultweightlist and this doesn't count on the 128 limit

Usage

Warning:Opening bracket must be on the same line as $weighlist

$weightlist my_weightlist {
	<bone> <weight>
	<bone> <weight>
	...
}

$sequence my_weighted_anim "my_anim.smd" weightlist my_weightlist

Bones inherit weight from their parents, and all root bones start with a weight of 0.

$weightlist no_hands {
	"Bip01_Pelvis" 1.0
	"Bip01_LHand" 0.0
	"Bip01_RHand" 0.0
}

$weightlist head_and_arms "Bip01_Spine2" 1.0

$Weightlist UpperbodyBlend {
	"Bip01_Pelvis" 0.1 
	"Bip01_L_Thigh" 0.0 
	"Bip01_R_Thigh" 0.0 
	"Bip01_Spine" 0.2 
	"Bip01_Spine1" 0.4 
	"Bip01_Spine2" 0.6 
	"Bip01_Spine4" 0.4
	"Bip01_L_Clavicle" 0.8
	"Bip01_L_Upperarm" 1.0
	"Bip01_R_Clavicle" 0.8
	"Bip01_R_Upperarm" 1.0
}

PosWeight

optionally you can set posweight option right after bone weight value to also set weight for location translations on top of declared weight. Useful for blend different length skeleton animations or even disable position translations.

Note:posweight cannot be used when weight is already zero

Note:It doesn't really matter if posweight is double quoted

$weightlist rotate_but_dont_move {
	"Bip01_Pelvis" 1.0 "posweight" 0.0
}
