FTraitStackBinding | Unreal Engine 5.7 Documentation

API > API/Plugins > API/Plugins/UAFAnimGraph

To keep the node instance cost as low as possible, data such as pointers to the shared data are not stored per node and are instead fetched on demand. In order to be able to query for interfaces on a trait stack from a trait pointer, a trait stack binding must first be created.
