struct FRigVMFunction_MathTransformAccumulateArray : public FRigVMFunction_MathTransformMutableBase
Remarks
Treats the provided transforms as a chain with global / local transforms, and projects each transform into the target space. Optionally you can provide a custom parent indices array, with which you can represent more than just chains.
Variables
| Type | Name | Description | |
|---|---|---|---|
   |
TArray< int32 > | ParentIndices | If this array is the same size as the transforms array the indices will be used to look up each transform's parent. |
   |
FTransform | Root | Provides the parent transform for the root |
   |
ERigVMTransformSpace | TargetSpace | Defines the space to project to |
   |
TArray< FTransform > | Transforms |
