Peter Quint Posted August 19, 2012 Share Posted August 19, 2012 (edited) I think the issue is that when you create your mask you do not have any padding around your fog volume - thus it has values of 1 throughout. When you take this in to dops with the sopscalar field node by default the border type is set to streak - in other words for any place outside the bounds of your volume it just extends the value at the border, in this case 1. You can address this either by padding your volume a little in the isooffset node (use overide bounds) and or by setting the border type on the sopscalar field to constant, and the initial value to zero. By the way if you plan to animate the mask volume, you'll need to set the Time, and the SOP path to 'Set Always' in the sop scalar field node.
