There are three types of filter features available in Maya 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.
Elliptical filtering
- To enable, select
Advanced Elliptical Filtering under the
mental ray section in the
Attribute Editor of the file node.
Note: Elliptical filtering is only supported by mental ray for Maya rendering.
The filter types and their compatibility with the Maya software renderer and the mental ray for Maya renderer are specified in the table below.
