This section covers texture problems.
Problem: File textures are very noisy and not anti-aliased well, or File textures appear to shift or shimmer over an animation.
First check that the texture’s Blurmult value is non-zero. Next, change the file texture’s Filter type. The default setting is BLEND. The best compromise between speed and quality is QUADRATIC.
Problem: Procedural textures are very noisy and not anti-aliased well, or Procedural textures appear to shift or shimmer over an animation.
See Blur in Render > Multi-lister.

Procedural texture differences
Problem: Procedural textures aren’t quite the same on different platforms.
Procedural textures, or anything that uses a random number generator, will have minor differences from one platform to the next. For this reason, we recommend that if you are rendering a sequence of images, render the entire sequence on one platform.
Problem: An in-focus object next to a blurry foreground/background (Depth of Field ON) shows a jaggy artifact.
Render the blurry foreground/background separately, and composite.
Problem: Textures are distorted (stretched or squashed)
See Chord Length in Render > Multi-lister.
The surface may have uneven parameterization. Set Chord LengthON under the texture’s Surface Placement parameters.
