How can i acces index buffer data of staticmesh at packed game?

Hi! guys.

I want to acces vertex and index data of staticmesh at packed game.
Now i accesed vertex data by “Getting Transformed Vertex Positions” of Rama, but i can’t access index data.
I tried to access by using “Mesh specific vertices and triangles” of Rama, but it’s different with original index data.

Help me. please…
