After Creating a Blend Space and opening the asset, you will need to define the Axis Settings or properties that drive the blending as well as specify what animations to use as Sample Poses. With those two elements defined, you can further adjust your Blend Space by altering properties within the Blend Space Asset Details panel.

The first thing you will want to do is set up your grid by defining the Axis Settings from the Asset Details panel. The name to display for this axis on the Blend Space Editor grid also the name of the exposed pin on the Blend Space node inside an Animation Blueprint.

The number of sampled points from the animation data used for interpolating. Higher values give more precise results. This is displayed as gridlines in the Blend Space Editor grid along the axis for this input. Interpolation Time for input, when it gets input, it will use this time to interpolate to target. Used for smoother interpolation. Typically for multi-direction locomotion, you would define one axis as the Direction in degrees which you are moving and the other axis the Speed in which you are moving.

Please see the Locomotion Based Blending how-to page for a guide on setting up multi-directional locomotion with a Blend Space. With your Axis Settings defined, the next thing you will want to do is add some animations to sample from to the Blend Space Editor grid. You can right-click on a sample point to expand a roll-out menu with adjustable options for the sample.

You can change the location of the sample by adjusting either Axis Value in the case above, Direction or Speedchange the Animation or adjust the Rate Scale. You can also edit sample values using the numeric entry boxes for the sample located in the upper-left section of the Blendspace Grid. In addition to using the roll-out menu to move the sample by changing the Axis Value properties, you can drag-and-drop the sample to a new location on the grid.

Once you have a few sample poses placed on the grid, you can hold the Shift key and drag the green diamond around to view the blend between poses. While holding Shiftyou can also hold the Ctrl key to show actual sample values while previewing.

When you release the Shift key, the green diamond will remain in its location enabling you to freely move the camera in the viewport to view the pose from different angles. The video below illustrates the effects of each option and you can experiment with each option to reach your desired effect. While defining the Axis Settings and Sample Poses are two of the more critical elements to setting up your Blend Space, there are other properties in the Asset Details panel that you can adjust to further define how your Blend Space is used.

This section enables you to define the Axis to Scale Animation and is useful if you have input interpolation, as you can specify which axis to drive animation speed scale. For example, for locomotion animation, speed axis will drive animation speed thus scale. You can set this to None if it is not applicable, Horizontal or Vertical Axis. As described at the top of this page, this enables you to define the Horizontal and in the case of a normal Blend Space, Vertical Axis properties that will drive your Blend Space.

When changing the number of grid divisions or the size of either axis is changed, any existing samples will be snapped to the closest available grid point. Those for which no valid position could be found are marked as invalid and will be drawn in red enabling you to reposition them manually on the grid. This section contains options related to previewing as well as informational properties, such as what Skeleton Asset is associated with this asset.

The default Skeletal Mesh to use when previewing this asset only applies when you opening the Blend Space asset. This section enables you to smooth out interpolation between sample poses on a per bone basis or per pose basis.

Define target weight interpolation per bone, this will blend in different speed per each bone setting defined. When target samples are set, this determines how fast you would like to reach the target and can improve blending. This section defines the mode used by the Blend Space to determine which Animation Notifiy to fire.Locomotion Based Blending. State Machines.

Animation Blueprints. Blend Spaces are used by placing nodes in the AnimGraphs of Animation Blueprints which take in value data to drive the blending of animations and the final animation pose. For a full walk-through of setting up a Blend Space for locomotion blending, see the Locomotion Based Blending how-to page. Blend Space nodes provide access to the sample parameter data and output pose of the Blend Space.

Blend Spaces rely on data being passed into the sample parameters in order to perform the animation blending. Each Blend Space node has input data pins for each sample parameter that is created during the Editing Blend Spaces process. Variables or outputs from other nodes can be wired to these pins to pass the necessary data to the Blend Space and drive the blending of your Sample Poses. The values passed to the Blend Space are generally variables calculated during the update cycle in the EventGraph or through gameplay code.

An example of the Direction and Speed variables being calculated in the EventGraph of an Animation Blueprint is shown above. The Pose output pin of the Blend Space node can be wired to the Pose input pin of the Result node in the AnimGraph in the simplest case. Or, it can be wired to any other input pin that accepts an animation pose as an input when a more complex animation chain is necessary.

Post Feedback.Blend Spaces are special assets which can be sampled in AnimGraphs that allow for 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.

In this How-to, we use a Blend Space to blend between walking and jogging animations based on the character's movement speed and movement direction. This will allow us to use the playable character that was created along with the Animation Starter Pack project. We need to delete this character from the level in order to spawn in as the character from the previous step.

Blend Space assets need a Skeleton asset to reference, here we are using a shortcut to create a Blend Space from this Skeleton asset which we called MyBlendSpace. This allows us to use a different animation when our speed is at max and we are not moving left or right, we are jogging forward. The default Blend Space does not include Walking states which our Blend Space does, so let's replace it with ours!

Locate the section marked Crouch in the graph and delete it to remove the warning error. By default, the Animation Starter Pack has bindings created for crouch which our project does not. For this example, we will remove the ability to crouch walk.

We are changing our movement speed based on if Left Shift is held and will alter our character's movement speed in-game.

Click Compile then click the Play in editor button from the Toolbar. When playing in the Editor, using WASD to move around, the character will now walk by default and blend between walking animations when changing directions.

If i can get it to work, i'll just have to create blueprints inheriting from this class and set the skeletal mesh and animations. This subject seems to pop up every now and then, there are a few post on the answerhub, and even a wiki by Rama, but all of them seem to assume that the BlendSpace is created in the editor.

As you can see, i'm trying several methods via the skeletal mesh component and the anim instance to animate the mesh with the blendspace, none of them works so far. I tried everything i could find related to animation and blendspace in the api documentation. I can spawn the blueprint, but the mesh remains static so obviously i miss something.

I tried to set this in the blueprint, and i can see the debuging flow correctly going through everything. I can't check visually the blendspace, so i'm a bit lost and dry now.

Here's the code: Code:. Last edited by uced ;PM. Tags: None. Edit: I should have read your entire question. I'm interested in this so I'm going to help you get the bottom of it!

You're probably missing an update call somewhere, or you need to serialize the result to an asset or something. I'll report back. Here's a compiled simple animation blueprint. Note that the Character class doesn't appear to call or update the animation - it only sets it initially.

Tags: None. You could even blend between animations without a blendspace. Just take a look into animation blueprint of the third person template. There is a state-machine that blends between a looping blendspace for idle-walk-run that should loop to a non-looping "Jump-Start" followed by a looping JumpLoop and yet again a non-looping Jump-End.

So if you would blend between your 3 anims you could just add 3 states in your state machine and blend between them in various ways linear, cubic, If you would do that all the time without any need to keep that modular then I would screw them together in my 3D-application. If you would just add one animation sequence after each other without any requirement for blending then you could do this via AnimationComposite or AnimationMontage.
