ConstArrayView< std::uint32_t > getBlendShapeTargetVertexIndices
&40;
std::uint16_t meshIndex,
std::uint16_t blendShapeTargetIndex
&41; const
Remarks
MeshIndex must be less than the value returned by getMeshCount.
blendShapeTargetIndex must be less than the value returned by getBlendShapeTargetCount.
The vertex position indices are stored in the same order as the deltas they are associated with. These indices can be used to query the associated vertices themselves through getVertexPosition. View over the list of vertex position indices.
Parameters
| Name | Description |
|---|---|
| meshIndex | A mesh's position in the zero-indexed array of meshes. |
| blendShapeTargetIndex | A position in the zero-indexed array of blend shape targets within the specified mesh. |
