Variables
| Type | Name | Description | |
|---|---|---|---|
    |
bool | bAllowStretch | If true, joints will translate to reach the effectors; causing bones to lengthen if necessary. |
    |
float | GlobalPullChainAlpha | A global multiplier for all Pull Chain Alpha values on all effectors. |
    |
int32 | Iterations | High iteration counts can help solve complex joint configurations with competing constraints, but will increase runtime cost. |
    |
float | MassMultiplier | A global mass multiplier; higher values will make the joints more stiff, but require more iterations. |
    |
float | MaxAngle | Maximum angle that a joint can be rotated per constraint iteration. |
    |
float | OverRelaxation | Pushes constraints beyond their normal amount to speed up convergence. |
    |
FRootPrePullSettings | PrePullRootSettings | Settings only applicable when Root Behavior is set to "PrePull". |
    |
EPBIKRootBehavior | RootBehavior | (Default is PrePull) Set the behavior of the solver root. |
Deprecated Variables
| Type | Name | Description | |
|---|---|---|---|
  |
bool | bStartSolveFromInputPose_DEPRECATED | DEPRECATED: When true, the solver is reset each tick to start from the current input pose. |
