# globalFkWeight

The solver global weight for the forward kinematics demands.

## Declaration

```swift
var globalFkWeight: Float
```

## Discussion

Discussion This weight is a multiplier for each joint’s fkWeightPerAxis. The recommended value range is the closed range [0, 1], where 0 means no FK demands influence, and 1 is no rig level modification.
