Render passes (2)

[johnnymech]

Hi all,

Im having problems understanding some of the render pass output options. I want to break down a scene into passes to speed up render time. I have a back ground and floor that doesnt move or change in one scene so its a waste of time to render it 100 times right?
I have a transparent sphere that casts caustics and shadow on the floor. How do I set up a render pass to render this information onto the floor when the floor isnt part of this pass?
If you know of a page or tutorial on this please share.

thanks =o))

Have you tried the built-in passes?
