Blending when using LinkAnimClassLayers?

Here is how I got blending working when linking / unlinking anim layers (Unreal 5.5):

  1. Generally follow the instructions here: Animation Blueprint Linking in Unreal Engine | Unreal Engine 5.6 Documentation | Epic Developer Community

  2. In your Anim Layer Interface (which defines the layers to your animation), be sure the “Bindings” are set to the “Default Anim Graph Node Binding” type:

  3. In your ABP which implements your Anim Layer Interface, click on the layer function and in the Details tab you should see blend times appear:


  4. In the ABP that uses the linked layers, add an Inertialization node after the linkage:

Caveat: Did not try this for multiple linked layers.
