Syntax
struct FAnimNode_LayeredBoneBlend : public FAnimNode_Base
Remarks
Layered blend (per bone); has dynamic number of blendposes that can blend per different bone sets.
Variables
| Type | Name | Description | |
|---|---|---|---|
 |
FPoseLink | BasePose | The source pose |
 |
bool | bBlendRootMotionBasedOnRootBone | Whether to incorporate the per-bone blend weight of the root bone when lending root motion |
 |
bool | bHasRelevantPoses | |
 |
TArray< TObjectPtr< UBlendProfile > > | BlendMasks | The blend masks to use for our layer inputs. |
 |
ELayeredBoneBlendMode | BlendMode | Whether to use branch filters or a blend mask to specify an input pose per-bone influence |
 |
TArray< FPoseLink > | BlendPoses | Each layer's blended pose |
 |
TArray< float > | BlendWeights | The weights of each layer |
 |
bool | bMeshSpaceRotationBlend | Whether to blend bone rotations in mesh space or in local space |
 |
bool | bMeshSpaceScaleBlend | Whether to blend bone scales in mesh space or in local space |
 |
TArray< FPerBoneBlendWeight > | CurrentBoneBlendWeights | |
 |
TEnumAsByte< enum ECurveBlendOption::Type > | CurveBlendOption | How to blend the layers together |
 |
TBaseBlendedCurve< FDefaultAllocator, UE::Anim::FCurveElementIndexed > | CurvePoseSourceIndices | Per-curve source pose index. |
 |
TArray< FPerBoneBlendWeight > | DesiredBoneBlendWeights | Transient data to handle weight and target weight this array changes based on required bones |
 |
TArray< FInputBlendPose > | LayerSetup | Configuration for the parts of the skeleton to blend for each layer. |
 |
int32 | LODThreshold | Max LOD that this node is allowed to run For example if you have LODThreshold to be 2, it will run until LOD 2 (based on 0 index) when the component LOD becomes 3, it will stop update/evaluate currently transition would be issue and that has to be re-visited |
 |
TArray< FPerBoneBlendWeight > | PerBoneBlendWeights | Per-bone weights for the skeleton. |
 |
uint16 | RequiredBonesSerialNumber | Serial number of the required bones container. |
 |
FGuid | SkeletonGuid | Guids for skeleton used to determine whether the PerBoneBlendWeights need rebuilding. |
 |
FGuid | VirtualBoneGuid | Guid for virtual bones used to determine whether the PerBoneBlendWeights need rebuilding. |
