Heya guys, I went with the solution over at <span class="Apple-style-span" style="border-collapse: collapse; "><a href="http://saqoosha.net/en/2009/01/08/1676/" target="_blank" style="color: rgb(92, 69, 32); ">http://saqoosha.net/en/2009/01/08/1676/</a><span class="Apple-style-span" style="border-collapse: separate; "> which is a chroma key. Unfortunately other issues I have with lots of viewport layers means I've gone with a simpler introduction. Thanks for all the suggestions!</span></span><div class="gmail_quote">

Except he wants the cube to mask whats inside it. I'm not sure offhand how to separate the external faces of a cube with its internal faces, so I'd suggest using two cubes: insideCube and outsideCube.<br><br>insidecube should only have internal faces, and no external faces.<br>
outsidecube is the opposite (no internal faces).<br><br>then use the following:<br>viewport.<span style="color:rgb(0, 102, 0)">getChildLayer</span><span style="color:rgb(102, 204, 102)">(</span>insidecube<span style="color:rgb(0, 0, 0);font-weight:bold"></span><span style="color:rgb(102, 204, 102)">)</span>.<span style="color:rgb(0, 102, 0)">mask</span> = viewport.<span style="color:rgb(0, 102, 0)">getChildLayer</span><span style="color:rgb(102, 204, 102)">(</span>outsidecube<span style="color:rgb(102, 204, 102)">)</span>;<br>
<span style="color:rgb(102, 204, 102)"><br></span>As long as the cubes share the same transformation info, I think that will work.<div><div></div><div class="h5"><br><br><br><br><div class="gmail_quote">On Fri, Apr 17, 2009 at 5:30 AM, CodeJockey1 <span dir="ltr"><<a href="mailto:codejockey1@gmail.com" target="_blank">codejockey1@gmail.com</a>></span> wrote:<br>

Simple solution:<br>
<br>
create a cube, and turn off all of the outside faces so the material only<br>
shows on the inside faces. Done!<br>
