I have been working on a Blender add-on intermittently for over a year during my spare time, and I'm proud to finally get to share it with you all!
The add-on is called 'Wirebomb', with the main goal of being the best add-on for setting up scenes for wireframe renders in no time. It's currently only supporting the Cycles render engine, but I think I can add support for Blender's internal render engine pretty easily (now on the to-do list!).
I made this add-on because I myself as a blender user felt the need of it. I love wireframe renders, they show off your topology skills in a professional looking manner. Blender has great wireframing tools, but it's missing this extra functionality which tie it all together. And sure, there are a few other wireframing add-ons/scripts out there, but I couldn't find any which fit my needs.
Find out more and watch a demo here.
I hope you like it!
