How to render mesh's wire WITHOUT modifier? I hell don't understand why we can't render 2D wires as viewport do anytime...
The procedural wire modifier is always the favorite issue !... This one is probably useful for many cases but it build solid structure which becomes resource-intensive when applied to a very large model and stupidly useless if we entend to make a basic visual.
Then, some render setting issues are often proposed but nothing incredible too...
Maybe an addon exists to do that work ?
If you mean render like this, Wireframe node is the key.
