I see what you mean when I look at the image and I genuinely appreciate your feedback. If I knew how to fix what you've pointed out, I would definitely fix it, it's just that where lighting and reflections are concerned in Cycles (The engine I used to render the image) it's mathematically, physically accurate. All I can say is that if the patterned part of the blade was supposed to have some red in it, it would have been there.That's not to say that you're wrong, quite the opposite. You can look all around you in day to day life at real, physical objects, and something about them doesn't look how you would imagine it to look if you were to draw it or paint it. I think this is one of those instances. Sometimes when drawing or painting something, I'll add in things which I know logically shouldn't be there, but which look more correct and don't cause that niggling feeling that something is wrong. Or I'll leave out something I know should be there. As far as I'm concerned, art isn't all about realism, it's about aesthetically and emotionally pleasing things. I do fully agree that the blade looks strange where the change in material occurs, it's just a little difficult to argue with a raytracing render engine and force myself to fix something I know should be there.Hope that makes sense. Thanks again for taking the time to write a long comment
