About mesh

In my work today, I added MESH to the character's components.

The results appear in the picture。

In the software, everything is normal.

But, in the game, it is stretched。

In the past, there have been such a situation, my approach is to remesh

But I want to know how to avoid this happening again。

Make sure you aren't using whitespace stripping when you pack the atlas. It may also be how the game toolkit you are using messes with your textures.
