shadowbox isn't working [Solved]

When I first installed R4 I played with shadowbox and it worked fine. I’ve since installed R4.2 and I cannot get shadowbox to work in either version now. I am doing a very basic setup. Create a polymesh 3d, click the shadowbox button, clear the mask and select a mask rect brush. But when I ctrl+click and drag, nothing happens. The shape stays as a box. I’ve turned ghosting on also. What am I missing? Thanks.

Feel free to delete this thread. I’m an idiot. I had my mask inverted.
