Hello! In this quick tip I go over a simple technique for combining two Mixamo animation clips with different forward directions using the Blender NLA Editor. I know some of you have asked about this in one of my older Blender Mixamo tutorials, so hopefully, this helps you out if you're still struggling with the issue. This fix should apply to any motion-capture animation used with your 3d characters from tools like Plask or Deepmotion and the like, so long as the animation has been pushed down into clips from the NLA editor in Blender.
