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
- Controls elliptical filtering.
- To enable, select Advanced
Elliptical Filtering under the mental ray section in
the Attribute Editor of the file
node.
The filter types and
their compatibility with the Maya software renderer and the mental
ray for Maya renderer are specified in the table below.
