I just took a quick look at your post, but if I’m interpreting your blendspace properly, you’ve set both the right and left ninja strafe animations at 180 degrees (which is the same as -180 degrees). That’s backwards; so, in effect, you have animations at forward (0 deg) and backward (180 deg). If you want right and left animations, you need to place them at 90 degrees and -90 degrees, respectively.
And the flickering is caused because you have two different animations set for backwards.
