I found 2 punch animations for Unreals Hero TPP, does anyone know where I can find more attacking animations or a list of all his animations? The one on marketplace has none 
The best way would be when you create your own ones -> just export the char as a fbx and then create your own anims in a 3d program 
There’s a free animation starter pack in the marketplace with more stuff, but if you want something specific you’ll probably have to do it yourself. Use the same skeleton and the stock animations will still work.
