[PBR]Better weapons and tools(更好的武器和工具)

Fixed the normal map of the copper sword and sorry for my slip-up.

I found that the armor patterns have always had issues. I have begun repairing and correcting them, please forgive me. I haven't played survival for a long time.

I feel guilty that the friends who support me always using the version with bugs.

I am designing the appearance of the spear, but because of my slip-up, I have decided to make sure there are absolutely no bugs before releasing a new version.
