FUAFOffsetRootBoneNodeData

API > API/Plugins > API/Plugins/UAFAnimNode

Adds a procedural offset to the root bone coming from incoming root motion. It can optionally fade this out over time (controlled by EUAFOffsetRootBoneNodeMode).

This allows a code-controlled character to still be influenced by root motion, e.g. during plant turns. It can lead to less foot sliding in a motion matching setup.
