# Bypassing the Blend Mode for Specific Data Types

Each animation layer can contain animation curve nodes that specify many FBX properties of different data types. For FBX properties of a specific data type, you might not want the animation in one layer to blend with the animation in another layer, such as for the boolean data types.

Each animation layer has a blend mode bypass flag for each data type defined in the header file fbxtype.h. To bypass the blend mode, you can get and set the value of the blend mode bypass flag to one of the following:

Value of Blend Mode Bypass Flag | Description
--- | ---
true | The blend mode in the animation layer is ignored. During evaluation (by using the FbxAnimEvaluator class), the value of the properties in the animation layer override the values in any previous layers.
false | The blend mode for the animation layer is used during evaluation.
