Hi, I want to download the apache animation tutorial but I just want the videos that talk about the following subjects:

-Lighting the scene using (HDR) image based lighting
- Rendering with Mental Ray and final gathering
- Creating an environment for the animation
- Rendering ground shadow pass
- Projecting ground texture
- Adding mountains to the background
- Creating cg sky using envSky
- Baking animations

Thank you.
