I was fascinated to recreate and render a scene having those features. And this samples is now what im bringing you, simplifying vray camera depth of field and motion blur.Before I go so far, I wish to provide a diffirence between motion blur and depth of field. Although its just a simple term, I just want to give some insights for the sake of the tutorial. Let us examine an image without depth of field and motion blur. Its nice but something is missing in the composition - the action and depths Depth of Field-The Depth-of-Field effect simulates the natural blurring of foreground and background scene elements when viewed through a camera lens. Depth of Field works by separating the scene in Z order into foreground, background, and in-focus images. The foreground and background images are then blurred according to the values set in the Depth of Field effect parameters and the final image is composited from the processed originals. Suppose there are two or three objects, one on the foreground, at the middle and on the background. The moment you focused your vision on one of the objects say on the foreground, the other will then become blurred - this is what we called the depth of field. Cameras can generate depth-of-field effects. Depth of field is a multi-pass effect. You turn it on in the Parameters rollout for cameras. Depth of field simulates a camera's depth of field by blurring areas of the frame at a distance from the camera's focal point . It can be attained at any given time at any given point. If you want to follow the tutorial, you can download the scene / model on this linkmax2009_scenefilemax8_scenefile[/color]In order to have the missile smoke trails you must have an Afterburn Plugins. Visit this site for more info about the plug-ins ]AFTERBURN . If you havent this one you might wait for my fire trails tutorials for soon to be here. After you open the file, adjust the time slider to frame 66. The image will look like this. To activate the missile fire trails, press 8 ( environment and effects). Go to atmosphere and select Afterburn and Afterburn Renderer. Then adjust parameters below. Be sure to have your Afterburn pluginns installedMaking some test render will give you an image with no depth of field composition. Now let us activate Depth of Field and focus to Silver Surfer. Select the normal camera on the scene and adjust the parameters as shown below. -Enabled Multi-Pass Effect -Select depth of Field -Target Distance at about 3.5m to 4.0 m -On depth of Field parameters activate us Target Distance -Activate Display PassesThen on Environment and Effects (F10), go to effects and select Depth of Field and adjust parameters same below and make some test render.If you want to focus on helicopter ( Sorry i forgot to include the helicopter pilot on the scene), adjust camera target distance at about 40.0m-42.0 m. Then make a test render. this will give you an image the same as below This now conclude the normal camera depth of Field. Next is the Normal Camera Motion Blur NOTE: FOR CONTINUATION Game MasterNumber of posts: 3177Age: 92Location: riyadh, saudi arabiaRegistration date: 27/09/2008
