I’m having a somewhat relatable issue but with a 2D blend space. I can get an idle, walk, and run in a 1D bs to work fine, however in a 2d bs I can’t get any walk right / left , run right/ left animation to work once I hit play, but if you are like me everything looks fine during the preview.
Here is the tutorial I followed to first set up my walk in my event graph of character BP , then I later added a blend space in my ABP.
