public void GetBlendShapeFrameVertices(int shapeIndex, int frameIndex, Vector3[] deltaVertices, Vector3[] deltaNormals, Vector3[] deltaTangents);

Parameters

shapeIndexThe shape index of the frame.
frameIndexThe frame index to get the weight from.
deltaVerticesDelta vertices output array for the frame being retreived.
deltaNormalsDelta normals output array for the frame being retreived.
deltaTangentsDelta tangents output array for the frame being retreived.

Description

Retreives deltaVertices, deltaNormals and deltaTangents of a blend shape frame.

deltaVetrices, deltaNormals and deltaTangents arrays must be of size = Mesh.vertexCount. Add Mesh vertices, normals or tangents to convert from frame deltas to full vectors. deltaNormals or deltaTangents may be set to null if there is no normals or tangents to be retreived for a frame.
