I imported a character model I made and rigged for a third-person game, but there’s a problem whenever I try to play the animations I made for it. The weight painting I did around the joints isn’t working, whenever they bend they look rigid and blocky instead of smooth, like they did in Blender before I applied weights. The animations I’m playing were made in Blender using the Action Editor, and when I play them in Blender they look fine, but in Unity they’re messed up. I’ve been messing with it and searching google for answers but I can’t find out what’s gone wrong.
This one may help you:
