I made a single-animation mesh in Blender that just rotates. Then I imported it into Unity. The mesh imported fine, but the animation wouldn't play even if I set it to play automatically. I tried Fbx and Collada, and neither worked. Then I noticed an error: I looked up the error and found a way to set the animation to be Legacy. However, it wasn't letting me mark it as Legacy, and I suspect that the file may have been read-only. Can I get help with this? Thanks!
