Is there some place where I can find help for meshing for the sims 3 with blender?

I just started using blender to mesh for the sims and I'm having problems when I import my .obj files to milkshape. It gives like superweird results. Is there some secret to it that I don't know. I'm quite new at the whole meshing thing so I might be missing something completely obvious.

Also, how do I save my .obj files so that the object groups are saved?

You can just post in the Meshing forums, no matter what editor you use (it's a good idea to mention "blender" in the thread title if you do, and also state which version you use).

When you have "superweird results", please post screenshots – people won't know what you mean unless you show them. It might also help to explain exactly what you do when you import to milkshape, in case you're missing a step.

The .obj export has a bunch of options on how groups are saved – how exactly are you exporting? A screenshot might be useful.

You might also want to have a look at the scripts I've written to import and export objects thus bypassing the need for MilkShape. They aren't perfect, but the more people using it and giving feedback the more we can sort the errors. The scripts are sticky'd in the Meshing forums.
