Pro Feature
The RBF Editor is part of the Pro edition and only appears when Pro is installed.
Modify, add, and delete corrective bone poses on your MetaHuman's body. These correctives interpolate between one another using Radial Basis Functions (RBF). As a driver bone on the body moves, the corresponding driven corrective bones blend into position via a falloff function.
Solvers & Poses
- The Solvers list holds the RBF solvers on the body. (This also defines the joints in a joint group in DNA.)
- The Poses list holds the
drivencorrective bone poses for the active solver. You can have as many or as few poses as needed to make your solver interpolate to all the corrective positions.
Click Edit to modify a solver. While editing, you can Add, Remove, and Mirror solvers (mirroring maps the driving bones left ↔ right).
Settings
Expand Settings while editing to choose the Function Type, the RBF kernel (e.g. Gaussian, Linear), with a live curve preview showing how the interpolation falls off.
Committing
Commit writes your changes into the body DNA; Revert discards them.
Note
While in RBF editing mode, you must click Apply Pose Transform Edits before switching to another pose. This is how you associate the changes with a pose. Please note these are still ephemeral until committed to the DNA.
