The following filter features are available as described below.
Pre Filter
- Blurs image before it is used for rendering.
- To enable, select Pre Filter under the File Attributes section in the Attribute Editor of the file node.
Filter/Filter Offset
- These are parameters for the selected filter type. The Filter attribute scales the size of the filter and lets you specify the amount of blur in the texture map. Use it as an anti-aliasing technique to refine file textures, reduce flickering, or to achieve special effects. The Filter Offset attribute controls the texture blur in texture space (not eye space). Use Filter Offset for a blurred effect instead of anti-aliasing.
- Set these parameters under the Effects section in the Attribute Editor of the file node.
