It fails.   \r\n\r\nThe Scene.renderlist only shows 1 item in it (the video renderer), the image control has clearGl already called on it, and has been nil'd (so it shouldn't exist anymore).    The non-cardboard control shows everything correctly; just when I enable cardboard mode it goes black with that error message.\r\n\r\nAny ideas what I need to clear up/reset that might be holding on that is interfering?\r\n\r\n\r\n\r\n"}}
