![]() ![]() Images can appear behind all objects, in front of all objects, or a combination of the two with objects showing in-between.Ĭompositing can be a render time-saver. ![]() A simple example would be a modeled UFO moving against a real sky and trees. The images can also be a sequence of pictures, so you may use captured video footage as a background for your objects. LightWave lets you do this, but also takes it one step further by letting you throw objects into the mix. ![]() The whole idea behind traditional image compositing is quite simple: take two or more images, and merge them into a new composite image. An image of the New York skyline would be the background image and the UFO would be a LightWave object.ĭisplaying background in the Layout window, particularly a color one, is processor intensive, so use this feature sparingly. You often use background images to merge live action and 3D elements, like creating the illusion that a UFO crashed into the Empire State building. Make sure to use similar-sized background images if you wish them to match. You can never have an object behind a background image, nor can you light a background image or cast shadows upon it.īackground images stretch to fit the Camera resolution and frame aspect that you are using. Background images are considered infinitely distant from the camera. You set this option on the Compositing Tab of the Effects Panel. That is, it will always appear in exactly the same position/location no matter which way you tilt or move the camera. The Background Image is similar to the gradient backdrop however, it is always registered to the camera. In addition, when you set an image as a background for the camera, the Display Preferences for LightWave automatically updates to set Camera View Background to Background Image. The method is run from a DOS prompt using the following syntax (one line): You must tell the program specifically what to render. There is no control machine and thus it is not a distributed rendering situation. The LWSN program has a third option that lets you render a scene without running LightWave. This problem creates an error in LightWave and on each ScreamerNet node. The computers don’t know that drive Y: is not on the host, just that it’s present.Īnother problem occurs when the hard drive where you save the images or animation is full. Map a drive from a different computer as drive Y:, for example, and set your scene to save the animations to that drive. The most common cause of ScreamerNet crashing is when too many computers try to write or read their information to/from the Host computers while the host renders.ĭo not use ScreamerNet to render on the host machine, but rather use it only as a server where the hard drives are found.
