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

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 in the Shading guide), 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.
