Using Anti-aliasing with cameras

Anti-aliasing is used to blur the hard edges of your models in the display so they do not appear pixelated.

Remove the grid from your current camera when using anti-aliasing because MotionBuilder applies anti-aliasing to the grid as well as to models. See Showing the Viewer window grid for more on how to disable the grid in the Viewer window.

1. Hide objects such as Nulls, lights, cameras, and skeletons as these objects are also antialiased when anti-aliasing is activated, and slow the frame rate and rendering time of your scene.
2. Activate Use Antialiasing in the Camera settings Render options pane.

   When this setting is activated, there is a brief pause as the scene is re-rendered. When this setting is disabled, anti-aliasing is not applied.

3. Double-click in the Intensity field to enter an anti-aliasing value to increase or decrease the intensity of the antialias blur.

   For best results, use a low intensity. The default setting is 0.78.

   NoteBecause anti-aliasing blurs the entire image, a high intensity value may blur important details.
4. Use the Sample Count field to enter the number of times each pixel is sampled to determine the pixel’s color. The higher the number of samples the more accurate the pixel color, but the longer it takes to render.
5. Activate the Use Accumulation Buffer option if you are using a computer with a hardware accumulation buffer.
   NoteIf your computer is not equipped with a hardware accumulation buffer, a software emulation of the buffer is activated.

The software emulation of the accumulation buffer may decrease computer performance. See Anti-aliasing settings.
