Hello. I draw a model of packaging material is polyethylene, top with a pattern, a transparent bottom. It is impossible to make a film visible in transparency .. if you put gray it is muddy ... but with a refractive index do not know what to do now to make up 1.04 if it turns light, with different noises bump probyval put anything good also nepoluchaetsya, natural does not work like ordinary polyethylene. I was looking for material for vray - nenashel (polyethylene with pimples found ... but I need a simple) ... tell me what I can do, what kind of noise supply, or may very package "mash". If kneading how to make it like a real polyethylene ...

Hello! Plastic packaging itself transparent material, certainly not perfect, but we can assume that a fully transparent. Remember boxes machines, in which one of the walls of a transparent polyethylene in general that it is not visible. In your same situation, only making visible polyethylene packaging, this reflection. Surely polyethylene packaging with carrots not matte and shiny. That's all that you need to do. Add highlights. Take an ordinary VRayMtl with black or gray diffuse (for contrast and not reflections, respectively). Screw Reflection, making the color sample Reflect gray. Just posted on reflection , not to get glass reflection, and more opaque. Refract do white or slightly gray, to be made perfectly transparent packaging. As for Bump is certainly better to bend the geometry package , but if you is difficult, you can look for a suitable texture. That's all that concerns the material. The main thing do not forget that the reflection - it is not only the strength of the reflections in the settings of the mat, but also proper studio environment, that is something that should be reflected in this material😉

Replace created vie ray transparent material packaging vie ray blend material while maintaining previously created. The coat layer remains transparent mat, put it in the base material is opaque. The slot card mix thrust mixing these materials- conventional black and white jpg. All that is opaque black, all white in the map will be transparent. If it turns out that on the contrary it should be prozrachnym- opaque, just dragged on the base coat, the program asks what you want to do: copy, sample or change. Choose pomenyat- swap.prosto map should be drawn in the desired 2 d editor.
