To access feature type parameters, click the gear icon 
on a feature type in the workspace. This opens the Feature Type Parameter Editor.
Tip: To always display the editor in FME Workbench, you can select View > Windows > Parameter Editor.
General
All feature types share similar General parameters, which may include Feature Type Name, Reader or Writer information, and Geometry.
In most Writer Feature Type parameter dialogs, you can also control Dynamic Schema Definitions. Some database formats accept Table or Index Qualifier prefixes on the output table feature type.
Feature Types
Each layer in the vector tile corresponds with its own feature type. A tile may have multiple layers and therefore multiple feature types.
Layer Name
This optionally defines the layer name, expressed as a string, and is written to the metadata.json file.
This field defaults to the writer feature type name but may be overridden so that several feature types map to a single target MVT layer. The typical use case is to have different feature types for mutually exclusive zoom level ranges.
Layer Zoom Levels
Minimum Zoom Level
The required minimum zoom level at which a tileset will be generated for the current layer.
Defaults to the Minimum Zoom Level writer parameter value.
Note: Specific tile files within the zoom level will only be generated if input geometries exist within those tiles.
Maximum Zoom Level
The required maximum zoom level at which a tileset will be generated for the current layer.
Defaults to the Maximum Zoom Level writer parameter value.
Note: Specific tile files within the zoom level will only be generated if input geometries exist within those tiles.
Layer Metadata
Layer Description
Defines the layer description, expressed as a string, and is written to the metadata.json file.
This parameter is optional and defaults to an empty description.
