I originally asked this over at the Nexus, but didn't get any help, so I thought I'd try my luck here.

I'm trying to edit the Alice Murray down to a wearable top and I'm having a few difficulties correcting the clipping, once I get it into the game.

I started with the original full body mesh, used Nifskope to pull out all the mesh parts (except "upperbody" and all the nodes with the starting with "Bip01") and the mesh worked in my game without only mild clipping.

I tried to correct the clipping in Blender, but after I import it and export it with Blender, it either crashes my game or doesn't show (i.e. shows as equipped, but doesn't actually display).

Based on this, I suspect that my import and export settings are incorrect. Could someone please check them for me?

Also does the fact that I'm not using the "upperbody" slot in GECK for this change the way I have to import or export this mesh?

And for the record, I've checked that the BSShaderTextureSet in NifSkope is set up correctly.

Current settings are here: http://www.thenexusforums.com/index.php?/topic/535425-newb-blender-importexport-question/ (for some reason, it's not letting me attach screenshots here)

For anyone who ever stumbles on this thread, I did find out what I was doing wrong.

Although I was creating clothing meshes that did not have a body attached, I did need to include a skeleton in the mesh.

For details on how this can be done and for a really good tutorial on how to make clothing, look here:
