plastic problem

Jon,

The link does not work...this does. I had a book mark from your backlight mat file...

Thanks.

Cool, thanks corey

Nice one J_bug, nice one. I think the reflections could be a bit brighter, but looks great.

thanx for the help guys, I'm working on the material right now ) You were right this thing lacks of reflection, I'm not really familiar with the falloff map, but using it right now. J_bug thnx for the scene, really good materials, I think the one without the backlight map is better.
But I still think this mat isn't translucent, I had it in my hand ) Maybe I have to have a closer look again )
The mat I used is a composition of vray and highlightonly mat, no reflections, bump map to simulate the glossiness. Environment color was light blue, and one omni for the sun. Now I play around with the material and change the env. and also the sun. I'll post the results.

thnx & ciao

Sure, no problem

Taking a closer look at some photos of those things in daylight I see that the reflection is even greater. If you want a truly realistic look, as Marc said, you should grab some nice HDRIs. Especially for the reflections.

The falloff map isn't really that important. In fact plastic doesn’t use the Fresnel falloff type as far as I know. I was just trying to simulate that unique shading caused by the translucency that I'm thinking of. You should play around with Falloff, it's very useful to simulate diffuse shading also.

You're probably partially right about the translucency. I'm sure there are different polymers used to create these things. All in all, I would think that they each have a diff level of translucency taking place but it's just not noticeable in some. If they are painted in the process, for instance, then the paint would probably make it almost unnoticeable.

Sounds like a cool project. Can you tell us what it's for?

I model such things in max to "unfold" them. I was curious if I could make some pics to demonstrate how it will look like, so I started to set up the environment, materials etc. I'll put some other models in the scene if I will have a good material for them )
