UBlendSpace::GetPerBoneInterpolationIndex

function Engine Since unknown

#include "Animation/BlendSpace.h"

Access: public Specifiers: virtualconstoverride

Description

Looks up the per-bone interpolation index for a bone within the pose being evaluated, returning INDEX_NONE if the bone has no per-bone smoothing override.

Caveats & Gotchas

• Data must come from a prior call to GetPerBoneInterpolationData for the same skeleton — passing a stale or mismatched pointer produces incorrect results.
• There's a second overload that takes an FSkeletonPoseBoneIndex and USkeleton directly, useful outside of a pose evaluation context.

Signature

virtual int32 GetPerBoneInterpolationIndex(const FCompactPoseBoneIndex& InCompactPoseBoneIndex, const FBoneContainer& RequiredBones, const IInterpolationIndexProvider::FPerBoneInterpolationData* Data) const override

Parameters

Name	Type	Description	Default
InCompactPoseBoneIndex	const FCompactPoseBoneIndex&	Bone to look up within the pose currently being evaluated.	—
RequiredBones	const FBoneContainer&	Bone container describing the pose's required bones.	—
Data	const IInterpolationIndexProvider::FPerBoneInterpolationData*	Lookup data previously built by GetPerBoneInterpolationData.	—

Return Type

int32

Example

Looking up a bone's interpolation index C++

const int32 Index = BlendSpaceAsset->GetPerBoneInterpolationIndex(BoneIndex, RequiredBones, Data.Get());
if (Index != INDEX_NONE)
{
    // Bone has a per-bone smoothing override
}
