Newbie help! I screwed up the faces somehow

plero

At some point I accidentally merged a foot vertex to under the arm. So I (probably wrongly) just deleted those stretched out faces. I then tried to fill the hole under the arm and in the foot but had problems. And when I finally did, they don't match the material of the main body any more. I've tried reapplying new material, I've also tried extruding from the edges instead of using FIll Hole, and looked at the normals and for any invisible faces/vertex but nothing fixed it.

Please help!

check if they are in the same smoothinggroup as the rest of the object

Thank you, but I've actually made it worse now before I could try the soft/hard edges. The material is gone from the body apart from the foot, and if I try to re-assign materials it only changes the foot.

The soften edge fixed it in a previous file, thank you! But it seems if I still try to put any new material then the body material vanishes/deletes.

Update: It's okay, I finally found the Hypershade and fixed it.
