Light in solid, meshes, with normal soft error....

Good, and State testing 2000 ways and and got one which seems that it can be simulated very well, actually the visible “cut” is still but… the view is not already! lol, “cover” the judgment material. Thanks to the emissive - ambient oclussion inside the material, giving dark colors, and manipulating the material instance… it seems that it “hides” cuts.
