Houdini has no Perform Window. If you want a Copernicus network on a projector, the only native route is the Composite View, and its menu bars and toolbars are painted inside the same GL surface as the image — so there is nothing to switch off. No pan, no zoom, no way to aim it either.

COPout draws the pixels itself. Wire a COP Network in, pick the screen, press the button, and the image goes up borderless at the network’s own resolution. Owning the window is also what lets it offer the things the native pane never could: fit modes, flips for rear projection, a grade on the way out, and an alignment you nudge a pixel at a time that is saved with the scene.

Built for the night itself — installations, live sets, projection work. Aim and focus on the test pattern before the content exists, cut to black between pieces, and let the playbar drive it.
