Photo-real 3D - A Farmhouse in Autodesk Maya and Mental ray

I have done this 3d farm house environment before(link is given below). That time i was not able to batch render it as an animated sequence in maya. Later I used a MEL script to store the preview render frame by frame. It is not the write way. But eventually it yielded a animated scene. Still i did not get the animated trees that i created using wind effect in speed tree.
