How can you Blend between multiple Blendspaces?

[Charles_Cox]

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:

Blend Spaces are special assets that can be sampled in AnimGraphs that allow for the blending of animations based on the values of two inputs. Simple blending between two animations based on a single input can be performed using one of the standard Blend nodes available in Animation Blueprints. Blend Spaces provide a means of doing more complex blending between multiple animations based on multiple values (currently limited to two).

The goal of Blend Spaces is to reduce the need for creating individual, hard-coded nodes to perform blending based on specific properties or conditions. By allowing the animator or programmer to specify the inputs, the animations, and how the inputs are used to blend between animations, virtually any type of blending can be performed using the generic Blend Space.

Did you read my question? It seems you just copied and pasted from the official document:
Blend Spaces in Unreal Engine | Unreal Engine 5.3 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?

If you mean you want to use multiple blendspaces in a single Animation Graph then you just have to follow these steps:

First go to your animation graph and in the state where you want to use your BS just drop any BS (doesn’t matter which one).

Then click on the blendspace then in the details panel you will see an option (blendspace) in front of this option will be a drop down menu with bind written on it. Click on it and choose expose as pin.

Then a blendspace selection will pop up in the BS you dropped in the graph. Just promote it to a variable.

Then you can change this variable by running branches in the event graph.

Use node “Layered Blend per Bone” into AnimGraph panel (and customize the values of the bone name and the blend weight)

Yes, you can do this! What you are looking for is a Blend Space Graph in the ABP! This differs from a BlendSpace Player, the asset you create in the content browser.

Like Unity a Blend Space Graph doesn’t exist as a standalone asset. Instead it lives in your AnimGraph and each Sample that is added contains it’s own AnimGraph to which you can add anything from Sequences, to Montage Slots, to more BlendSpaces.

You can also take an existing Blend Space and right click to convert to a Blend Space Graph.

Thank you, it works perfect.
