Adjust output image filtering
 
 
 
Tip
  • In most cases, you should test render a file texture in Render View when filtering because you may not be able to see the results in the views or in Attribute Editor swatches.
  • When bump mapping, set Filter to a low value (under 0.1). Filter is primarily used for anti-aliasing textures—distant surfaces are blurrier. This may cause a bump map to become smoother when further away. If you want the bumps to be smooth, use a small Filter Offset value for a constant blur.

To fix a noisy procedural texture that appears to shift and swim during an animation

  1. Do any of the following:
    • Increase the Filter and, or Filter Offset values to achieve a slightly blurred effect and reduce the sharpness that causes the swimming.
    • Create a file texture (see Convert a texture or shading network to a File Texture), then increase the Filter and, or Filter Offset values to achieve a slightly blurred effect and reduce the sharpness that causes the swimming.
    • Increase the Shading Samples value.
