[SOLVED] Help with Making Default Replacement Hair/Clothes

Hi.

1). These things are not related to texture, those are sharp edges.
By default, the game shades everything as smooth. When you have a sharp (close to 90 degrees and less ) edge shaded as smooth, the dark shadow along it appears. To tell the game that this edge needs to be shaded as sharp, you need to split it.

When you import a mesh into s4s, the software splits it along the borders of all uv islands. This has something to do with the fact that a vertex cannot exist in more than one place on a uv map, but the reason is not important. The important part is that, if an edge is not split when you import it in s4s, it will not be shaded as sharp. But if it is already split by you, it will.
So:
1). a creator creates the hair, imports it in s4s, s4s splits it, but does not shades these edges as sharp;
2). You export a mesh mesh that is already split;
3). You re-import a split mesh, s4s shades those edges as sharp.

So, to avoid this, you need to Remove doubles with Merge distance set to 0,0001. This will merge those vertices that s4s split

2). What you import in the package must have the same number of meshgroups as what is being replaced.

I suggest you to just hide those ugly bg items instead of overwriting them.
