public RemoveIfNotAttribute (object condition, bool overridePriority, string filePath, int lineNumber, params string[] keywordNames);

参数

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.
