I’m in the same boat as OP. I followed the 3rd person tutorial from start to finish. Everything was working. Yesterday I used my store credit to buy “prototype characters” from the market place, I added them to my project and then in the “My Character” blueprint I went into the viewport tab, selected my hero model and in details > mesh, I swapped out the default hero from the tutorial to the “prototype character”. When I compiled and went to play, he just slides around in a t-pose without animation. So I went to go change it back to how it was, and now the original default character, has also lost his animation and now my project is broken.
I don’t want to start over, I want to learn how to fix this. So, how do I fix the default character again, and once I know how to do that, how do I properly swap it out for the “Prototype Character”. That way I can fix things I break and also get the hero replaced as I intended.
Thank you so much.
EDIT/ADDED: I should note, that everything appears to still be hooked up properly, all I did was that one change, and then put it back. If I go into the default tutorial characters animation blueprint the skeleton > mesh > animation > graph views all look right, and there he still has animation playing and he still has his idle-walk-run blend and his punching montage working and available, but compiling and running the game, he’s still currently broken and sliding around in a t-pose.
