Ocean Surface in FG reflecting light from footage in the BG

[ocamp]

Hi there,

I had an idea to make a standard ocean simulation to have as stock footage for future shows.

Basically the premise is this,

Layer 5+ = Additional footage to superimpose over top of the other layers
Layer 4 = Video Router for Layer 2
Layer 3 = footage layer for lighting in the background
Layer 2 = Video Router for layer 1
Layer 1 = ocean simulation footage layer

I want to have the water layer reflect lighting and colors from the background footage, but in real-time, so it matches whatever footage I throw at it in the future.

I'm not sure how to do it, and I have no clue if I have to do something in particular to make it work (i.e. use grayscale color mapping or something like that.)

Any help is greatly appreciated.

Thank you!

How about Mirror and Goo?
