white polycarbonate panels material problem

[Alyosha]

I'm having difficulties tryint to simulate the semi-transparent white polycarb panels as seen here http://www.sepitalia.com/cmscontent/gallery/images/111_20110904_150656_20.jpg

 

I find it impossible to retain this kind of vibrant whiteness in a semi transparent material, it usually just goes grey or something.

 

Any ideas of how to go about this challengE?

Are you using transparency or refraction? That might be your problem. For plexi-glass/polycarbonate I'd suggestion tweaking the refraction of your material to get the desired result.

 

As a work around you can create a VRay blend material with your base polycarbonate material (using refraction) with an additional layer of a VRay light material. Tweak the blend amount until you get the desired brightness.

Hey, thanks for the tips, but I was using refr all the time...even glossy refraction and still it produces grey panels not white, even tho i'm using 255 white mat......:-(

 

i've tried the light mat+blend mat and it's a bit better but i'm having problems retaining the desirable level of transparency this way...

 

tried translucency but even though my scene is physically correct and i've assigned proper depth to the material it doesnt work at all:confused:

Never mind, I figured it out........I was being stupid and had physical camera white balance settings messed up, so all white materials would come out yellowish at best.....
