Mask help

Hi everyone... I have a precomp that has been turned into a 3D layer. I duplicated the precomp, and added a 50% mask to each layer. The bottom layer's mask is set to add, and it reveals the left 50% of the precomp, and the top layer's mask is set to subtract, revealing the right 50%. (The two halves are going to swing open in the middle like doors.) Everything looks great, except for a tiny little one pixel seam down the middle of the image. Without using expansion or feathering, does anybody know how to hide the seam?
There was a tutorial somewhere on the net about handwriting that said there was some button or switch that could be selected that would hide mask seams where the edges of masks butt together. But I can't find the tutorial, or a solution.

If you are just using masks (as opposed to using mattes and stencils) why not just make one mask 1 pixel wider or split the difference? Select the mask and use the arrow key to move it.
You might be thinking of setting the top layer to "alpha Add" when using mattes/stencils because that fixes the 1 pixel gap.
Just a thought.
Good Luck,
Don
