Black borders (letter box) appears in render

The black borders define the film gate.

See Ignore Film Gate in Render > Globals .

Set Ignore Film Gate ON under Render Globals.

Rendering image matching views

Problem: The rendered image does not match the view in the modeling window or camera.

There are several possible causes:

• The rendering aspect ratio may be different from the modeling window aspect ratio.

  Set the window resolution to be the same as the rendering resolution.

• The camera’s film offset may be greater than or equal to the camera’s film back size.
• You may have used Render Active, and the dag items under the camera were not selected in whole.
• You may be using motion path curves with knot multiplicity.

  Rebuild the curve or select CurveTools > Use result from Animation > Editors > Action Window .

Color banding in rendered image

See Film Grain in Render > Multi-lister .

Set Film Grain to 0.01 in the environment control window.

Overall image is too sharp

See Post Filter in Render > Globals .

Set Post Filter ON under Render Globals, and set the Post Center, Post Adjacent and Post Diagonal parameters to 4,2,1.

Incorrect lighting, view, or texture placement

Zero transforms for a light, camera, or 3D texture placement objects causes problems.

Do not select Transform > Zero Transforms for a light, camera, or 3D texture placement object. If you do, you must go through the affected portion of the hierarchy (the SBD window is useful for identifying this), and ungroup and retransform the light, camera, or 3D texture placement object.
