A shot landed on my desk where wave op was used as deformer. It has made the polygon normals unusable for my work. I am looking for a way to reorder normals back to their usual state.
I tried to use the JV_FixNormals.xsiaddon as well but that does not seem to be compatible any more with softimage 2010. It installs fine but does not appear in menus, in plug-in manager it only adds the folder without commands :/

Here is the shot from messed up normals:

Thank you!

Is there non-uniform scaling? Try freezing the scaling or the transforms.
