====== Filter layer editor ======

The //filter layer editor// allows you to modify [[plugins:calc:atFilterAM:filters#layers|filter layers]]. This dialog box is opened from the [[plugins:calc:atFilterAM:filtereditor|filter editor]], and looks like this:

===== Climate and land type =====

The climate and land type drop-lists allow you to set the desired climate/land type for this filter layer, which is used when [[plugins:calc:atFilterAM:filteram|filtering the attributes map]]. The climate/land type selection also determines the type name and texture name reported when generating alpha maps ([[plugins:calc:atfilteram:alphaexpress#When you click OK|see here]]).

===== Layer strings =====

The layer strings, are the text strings used to match the filter layer with the attributes map land type. A string such as "grass" will match-up with any land type that has "grass" anywhere in its name. Multiple strings may be used to match with different land types. For example, a layer with strings for "rock", "pebble" and "cliff" will produce a merged output alpha layer that combines all land types with "rock", "pebble" or "cliff" in their names.

The wildcard "*" may be used to match the filter layer with any land type in the attributes map. This is typically used for the 'default' filter layer.

<note>
Strings are not case sensitive.
