Can any one shed any light on why an extra white square box has appeared on my shape layer and how i can get rid of it?
I've used a shape layer to cover up a shot of a camera man in a mirror. The shape layer is black with extra blur and grain added to it. Plus it's been feathered.
I've animated the shape layer to move with the shot by changing it's path every frame.
All this is fine and has worked to obscure the shot of the camera man in the mirror.
However a new white square (see image here: http://www.adam-laurie.co.uk/?p=471) has appeared in the centre of the shot. The new white square stays visible while the shape layer is visible. (Turn off the opacity for the shape layer and the extra white box disappears).
The white box also appears on the final footage when rendered and exported out.
