I'm setting up to do the FW-190 tutorial and have reached the point where I'm not going to be able to actually see the rotoscope model I'm supposed to be modeling. Specifically, the grid is in the way. I've tried setting the grid size to 0 but it still persists in being there. How do you hide the grid, or failing that, how can I place the rotoscope image in front of it? (I notice that in the tutorial photos there is no grid at all.)
