How can you Blend between multiple Blendspaces?

For my animation BP, I have several Blendspaces I need to use. My goal is to blend between the various blendspaces using 3 different Parameters. How can I do this in the anim Graph? most examples I seem usually just use two parameters. Any help would be greatly appreciated since I’m a bit new to Unreal. I’ve done this in Unity using Unity’s Blendtree, and would like to do a similar approach:


Did you read my question? It seems you just copied and pasted from the official document:
Blend Spaces | Unreal Engine Documentation

I wasn’t asking what blendspaces are, I know what blendspaces are. I have several of them already created, each of them driven by 2 values. However I have a total of 3 different values I need drive the animations off of. I need to figure out how to blend between the different blendspaces if it is possible.

I am trying to do the same thing, also for some flying animations. Did you ever figure it out?
