The new Modular Control Rig system in UE 5.4 makes the rigging process much more easier that the traditional 3D workflow. This revolutionary tool steamlines the rigging process, allowing UE user to quickly set up a robust animation rig for ant character or skeleton.

With the Modular Control Rig, artists no longer need to spend days or weeks building complex rigs from scratch. Instead, they can quickly assemble a fully functional rig using pre-built components, each designed to handle a specific part of the character’s anatomy. This modular approach not only speeds up the rigging process but also ensures consistency across multiple characters or projects.

To get started with the Modular Control Rig, follow these steps:

1. Create a new Modular Control Rig asset
2. Assign the character skeleton to the rig
3. Drag and drop modular components onto the character’s sockets

Create Control Rig Asset

1. right-click on your Skeletal Mesh Asset and select Create > Control Rig. This creates a Control Rig Asset in the same directory with the postfix _CtrlRig. Double click the Asset to open it.

Remember to manually assign the Skeletal Mesh to your Control Rig Asset after opening. This is done by clicking Import Hierarchy in the Rig Hierarchy tab, then specifying your Skeletal Mesh.

Rig Hierarchy

The Rig Hierarchy panel is used to view and select your control hierarchy in an outliner-type view. This is also the primary area to create new Controls, Bones, and Nulls.

Create these elements by right-clicking in the panel and selecting New > Control, Bone, or Null. Your selection determines the location where these elements are created. If nothing is selected, then new elements will be created at the origin (0,0,0).
