Hello everyone, first of all I want to thank each and every one of you for the help you are giving me, thank you very, very much, I appreciate it very much. To understand what I'm looking for, let me explain that, as I already mentioned, I work for a very, very large company worldwide that makes self-adhesive labels, and our clients are the top of the top, what I do is generate the labels and packaging. of new products or new presentations of said products, these can be for personal care, drinks, food, in short, any product that can be found in a supermarket, these labels generally consist of different finishes, shiny, matte, hologram, iridescent , metallic, transparent, textured, heat sensitive, UV, even LED light, it is like making special effects but printed, and the combination of these effects is practically infinite, they can have one or more effects, up to 9 or 10 effects per label , the point is that depending on the materials each effect can behave differently, and that is why I need to find a way to project a reflection different from that of the background, imagine a label made up of 5 or 6 layers, one transparent, another shiny, another opaque, the next metallic, another one with a tactile texture, and the last one iridescent, each one reflects the different background, but to sell that label to the clients you have to "make adjustments", this is where through the reflection you can add luminosity, brightness, highlight the reflections or if necessary reduce them, that is why the reflection field of the mentalRay materials were so useful, each material could be adjusted individually, even having a different reflection which made them more attractive, that is what I was looking for , it is actually very simple, let's say it is adding a reflection map to each material to be able to make custom adjustments, just as you can do in the standard 3D studio materials, the problem is that these materials do not work with Arnold.
I have not been able to put his recommendations into practice due to lack of time, but as soon as I can I will do so, and I hope to soon be able to show you the result of this search, thank you very much.
