Add-on for wire renders with Blender internal and Cycles
A wire render has a lot of uses in architectural visualization and most of them involve the demonstration of the structure of a 3d model for other artists. I ask all my students to produce a wire render of their 3d models to evaluate their work. In Blender we have to create a setup of two objects in order to create a wire Render, giving to one of the objects a material with the wire type selected, and adjust the wire with the Z Offset parameter. This works really well, but demands some work to setup all materials and to create the duplicates of the objects.
An add-on called Setup Wire Materials can speed up the process! The add-on was created by an artist called liero and is available to download at this thread in the Blenderartists forums.
The Add-on is quite simple to use, and for those of you that want a preview of how the add-on works, the video is a nice overview of the Add-on.
Rendering wires in Cycles
As a plus, the Add-on can create a duplicate of any 3d model, based on the wire structure. Why? The same workaround to render wires with the Blender internal render doesnâ€™t work on Cycles. To be able to render wires in Cycles, an option called Create Wire Object of the add-on creates a polygonal copy of any object, using their edges to build a new object. This way we can see wire renders on Cycles. But, be aware that this process is really slow, and can demand some time, especially with dense meshes.
