O.K, So my last version of the trench dive still sucked, i went back and rebuilt some of the peices. Its the lighting thats so tricky, i got lighters block.

So then i discovered that when this shot was put together in the original film they used a mat painting, the laser flashes were used to cut to the bit where the camera dives into the actual trench at the last minuet, since i can get the lighting somthing like from 1 angle ( when i move the camera round it blows out the render ) i am going to do a very high res still to zoom into in post, then i will just animate the trench bit.
