Cheers Marlon,

I've not got any lights in the scene, it's completely illuminated by Final Gather, I'm not entirely sure of the in's and out's of FG but it's got something to do with the fact that the whole 'sky' is illuminating the scene and a new FG map is calculated with each frame so the shadows fall directly under my model in each frame.

I made this picture which will make it clearer (I hope!). The red arrows represent the FG rays, they're bouncing all over the scene, when they encounter an object they will bounce off it (illustrated by the green dots) and a shadow is created underneath (or around) the object. Not very technical I know but I hope it sheds a little light (no pun intended) on the matter.

Take it easy,

Mat.
