// Regarding to the image data and FBTexture class in OR SDK (MotionBuilder)

// In theory you are able to put image frame index direcly to that GetImage method
//  that should return GLubyte *data of a specified frame
// but in practive it will produce error for future MoBu drawing
// the way out is to...

// 1 - first of all, specify the current frame with "CurrentFrame" property

// 2 - execute GetImage() function with a argument -1 by default
