| condition | Unity compares the data field to this value. The outcome determines the filter behavior. |
| overridePriority | Whether this filter attribute overrides filter attributes that are already active on the same keywords. The default is false. |
| filePath | The path of the file this attribute is in. Automatically filled by default. |
| lineNumber | The line number of this attribute. Automatically filled by default. |
| keywordNames | An array of shader keyword names the filter attribute will apply to. |
Remove the specified shader keywords from the build if the data field doesn't match the condition.
