D3DXLoadMeshHierarchyFromX loads the animation data and frame hierarchy from a x file.I dont think it mean anything to vertex color.After all I did it, simply By using D3DXLoadMeshFromX. But it doesn't look like that of 3dsmax model. Perhaps every vertex color I specified , has been combined with it's diffuse color and finally put into material buffer, Can anyone guess why vertex colors seems to be zigzag. thanks guys anyway
