I created a game character that looks good in Blender. However, after exporting it to Unity, her shoulders appear weird. It looks fine in its default state. Here are screenshots:
It looks normal in Blender.
But in Unity, it looks like this: her shoulders are too sharp, and her outfit looks odd.
Okay, I’ve fixed it. The problem was in the quality settings. In Project Settings → Quality → Skin Weights, I set it to 4 bones, and then it became normal.
