The type of blending algorithm that the blend tree uses.
| Simple1D | Basic blending using a single parameter. |
| SimpleDirectional2D | Best used when your motions represent different directions, such as "walk forward", "walk backward", "walk left", and "walk right", or "aim up", "aim down", "aim left", and "aim right". |
| FreeformDirectional2D | This blend type is used when your motions represent different directions, however you can have multiple motions in the same direction, for example "walk forward" and "run forward". |
| FreeformCartesian2D | Best used when your motions do not represent different directions. |
| Direct | Direct control of blending weight for each node. |
