Use Spherical Limits

When enabled, spherical limits will be evaluated.

Spherical Limits

When Use Spherical Limits is enabled, you can add spherical limits to the array. After adding an element, it's properties include: Driving Bone: Bone to attach the sphere to. Sphere Local Offset: Local offset for the sphere, if no driving bone is set the is in node space, otherwise bone space. Limit Radius: Set the radius of the sphere. Limit Type: Whether to lock bodies inside (Inner) or outside (Outer) the sphere.

Use Planer Limits

When enabled, planer limits will be evaluated.

Planer Limits

When Use Planer Limits is enabled, you can add planer limits to the array. After adding an element, it's properties include:

Enable Wind

When enabled wind is factored for the bodies in this simulation.

Wind Scale

Set the scale to apply calculated wind velocities in the solver.

Remarks

Driving Bone: When using a driving bone, the plane transform will be relative to the bone transform.Planer Transform: Set the transform of the plane. This is either in component space if noDriving Boneis specified, or in bone space if a driving bone is present. Set theX,Y, andZvalues for the planeslocation,rotation, andscaleproperties.

Skeletal Controls

With Skeletal Control Animation Blueprint nodes you can take direct control of a character's Skeleton asset. Skeletal Control nodes can be used within a character's Animation Blueprint, on the AnimGraph, to control an individual bone, create IK chains, and other procedural, dynamic bone-driven animations.

Skeletal Control nodes are structured similarly to other AnimBP nodes. The node can receive an animation pose through the input pin and generates a modified pose through the output pin. Most Skeletal Control nodes operate and compute transforms in the Component Space. Animation poses generated in Component Space calculate bone transforms relative to the Skeletal Mesh Component of your character as opposed to the bone's Parent Bone. Component space pose pins appear as blue in the Anim Graph.

You can convert poses from Local Space to Component space with space conversion nodes.

Space Conversion nodes have an associated cost to your project's performance. It is recommended that space conversions occur as infrequently as possible by grouping specific space reliant functions together, near the final pose node when possible.

An alpha value is also common among Skeletal Control nodes. Similar to Blend nodes the alpha value controls the degree of applied modification to the source pose, when generating the new pose.

In the case of Skeletal Control nodes, a float value between 0.0 and 1.0 is used as the alpha value to determine the weight of the applied Skeletal Transform. A value of 0.0 gives full weighting to the input pose, while a value of 1.0 gives full weighting to the control's computed Transform.

Within the Details panel of each Skeletal Control node, you can also set the LOD Threshold in which the node is considered. The value defined as the LOD Threshold will be the highest LOD level the Skeletal Control node will be used. Any higher LOD levels, (lower quality models), will ignore the Skeletal Control node.

By restricting the LOD level Skeletal Control nodes to compute bone transforms, you can reduce the performance cost of your animation system.

Here you can reference additional documentation about each of the Skeletal Control Nodes you can use in your projects.
