Hey, I am going to export my object that is rigged from blender into another 3d program to correct the vertex normals and then import back into blender. Then re-parent the mesh to the rig.
Question: Will I have to reassign the vertex groups to the bones and re-rig everything?
:spin:
what is wrong with your vertex normals that you have to export it?
have you tried selecting all the verts in edit mode and pressing cntrl+n ?
this will recalculate the vertex normals when they go a bit spazzo
Okay, thanks for advice. I’ll give a try. I did try this once, but not all of the vertices were selected, just the ones that were rendering as faceted ones (rather than smooth like the rest).
select them all and hit the set smooth button 
you can set part of your mesh to be smooth and part to be solid
and you can mark edges and set them sharp and then with the help of a edgesplit modifier, make only those edges appear sharp.
i never use the "some parts smooth, other parts shar"p approach, i set the entire mesh smooth and define the sharp areas by marking edges and adding an edgesplit modifier.
By the way, if selecting all and using ctrlN does not correct your (vertex) normals, you probably have a flaw in your mesh somewhere. Ctrl N never failed me so far, only time it has, I found out I had a few small internal faces left I forgot about.
Smooth faces did the trick.
Appreciate the help.
