Guys, theres some easy way without wireframe modifier to show in render the wireframe from a model? Thanks in advance!
Turn on wire display and do an OpenGL render (icon on 3d view header)
In cycles use the Wireframe node to influence colour of the wireframe

oh, this addon is useful! Thanks a lot Richard!!!
