42 * @brief Specialized MotionIndex to control blend shape.
43 * We can control the blend shape by index (when we set BlendShapeId as IndexKey),
44 * or by name (when we set BlendShapeId as StringKey).
46 * MotionValue should be float type.
50 * BlendShapeIndex blendShapeIndex0 = BlendShapeIndex::New("nodeName", 0u);
51 * BlendShapeIndex blendShapeIndex1 = BlendShapeIndex::New("nodeName", "Target_1");

54 * BlendShapeIndex blendShapeIndex2 = BlendShapeIndex::New();
55 * blendShapeIndex2.SetModelNodeId("nodeName");
56 * blendShapeIndex2.SetBlendShapeId("Target_2");
60 * Specially, if ModelNodeId is Property::INVALID_KEY and BlendShapeId is StringKey,
61 * It will control all ModelNode that has the inputed BlendShape name.
65 * // If "node0" and "node1" has same BlendShape named "Smile",
66 * // blendShapeIndexAll will control both nodes.
