[4.6.1] No solution left in AnimBlueprint

Guess I found another “No exit” problems…where none solution exist and we need to sacrifice something…there are somethings I want to do but I barely knows how to accomplish that:

  1. How can I blend multiples slots with the function Layered Blend per Bone like the image below…because i used two slots…and or I lose the animation of first one or the second

  2. I have two Aim Offset…they work fine and i want to know how setup them to play depending the result of boolean…

  3. Why the Blend Poses by Bool ignored the logic I bought before?

  4. How plug all this in the final pose ???
