Multi Blend 2D Playing Incorrect Animation

[Kh4iri]

Issue description:
Occasionally, the Multi Blend 2D plays an incorrect animation. This problem typically arises when both the X and Y values are non-zero. For instance, in the video provided, the Y value is 100 and the X value is -100, yet it triggers the right strafe animation instead of the left strafe animation.

The issue is that the engine uses triangulated blending, so imagine triangles drawn between the dots. The interpolation of those points outside of the triangles isn't very intuitive which should be fixed imo. But if you keep the values within the triangles, it works correctly.

For this system to properly work you really need 8 directions of movement.

Ah thanks for the explanation! I got it working using your solution. I also agree that this issue should be fixed or at least mentioned somewhere.
