Ok I wanted to create a new mesh buit of an exsisting one. The idea was to convert a pair of heels and a dress for male sims. However I have only had a small bit of experience with Mesh editing from Oblivion but nothing too extensive. So I am in need of a tutorial and list of stuff i may need for this.

If I am successful with just a few meshes I may convert all female clothing to male. Yet I am still unsure if this is possible.

You're not going to find a full tutorial for that. But basically, you need CTU (to extract an existing mesh and then put your edited mesh in-game), Milkshape (to edit the mesh) and Q-Mesh (a Milkshape plugin that will let you work with TS3 body meshes). Beyond that it's mainly a matter of just reshaping the body. If you look at my hair tutorial, it should at least get you started (and provides links to the stuff I mentioned). I think daluved1 was working on a CTU manual too, that may have a bit more info on using it for meshes.

Ok Thanks I will have a look at that and see how things turn out.
