Hi,

there is also a method described here... "Single Sided Wireframe Rendering in Maya (all geo types!)"... -->
https://www.geocities.com/jozvex/tuto...wireframe.html

Provide3D has some plugin's e.g. NurbsData for Nurbs which will render the nurbs in wireframes... -->
https://www.provide3d.com/

I believe these plugins also can be found on Highend3d... there is a 30 day trial demo for download... if you are going to try them I will strongly suggest you backing up the scripts they will overide e.g. the Hypershade.mel since when the demo expires you can't get your hypershade to work before you have the original non modified script back... it really sux...

regards
