First, base Material class does not expose the Brush property, so you must hunt for a concrete material such as DiffuseMaterial to get the actual brush. Second, the poster reports issues with objects other than the intended object getting partially invisible, etc.<\/p>\n<p>The approach with transforms &#8220;to nowhere&#8221; seems more attractive, but it kinda reminds me of the days when people put windows at &#8220;large&#8221; negative coordinates (say -1000,-1000) to make them &#8220;invisible&#8221;. It worked fine for a while, but turned out quite ugly when 1200&#215;1024 double-monitor setups became common. If you make your right monitor a primary, the left monitor gets negative coordinates, and you suddenly see all those windows crowded in the bottom of your screen.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>This is not as easy as it might have been.
