# globalFkWeight

The solver global weight for the forward kinematics demands.

```
var globalFkWeight: Float
```

## Discussion

This weight is a multiplier for each joint’s [`fkWeightPerAxis`](/documentation/RealityKit/IKRig/Joint/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.
