i'm modeling an hard surface with subdivision, bevels and so on. I would like to bake the final wireframe to texture, with all the subsurf, bevels, bools etc. Is it possible?
I'm not sure this is exactly what you want but you could duplicate your object, apply all the modifiers to the copy, in Edit mode/Face Select mode, select all and inset individual faces (double i), give a color to the selection, invert selection and give another color to the wireframe, then bake the result?
Wireframe node should be possible to bake as any other material ... it just goes to triangulated. Probably because all meshes are triangulated for rendering?
