Hello all,
Long time renderer, first time forum poster. I need some help getting a model to render correctly. My model (built in SW'12) is of a clear, dual walled container (similar to a Tervis tumbler). My problem comes when I set the materials, it seems that having two clear objects so close makes the inner one really dark. I've tried "transparent plastic," "solid glass," and regular "glass" settings; tweaking the brightness/gamma/transparency/AOR and double sided option. I've also tried inserting lit objects inside and in between the two objects, nothing works.
Can anyone give me a tip on how to get the inner part of the cup to look as transparent as the outter part?
I included an image of the model rendered using "transparent plastic" and the "HDR studio bright" on the default settings for reference.
First, make sure there is a small gap between the layers, like .005 - .010 or so. If it's an assembly you can scale (mold tools) down the liner just a tiny bit. Make sure the outer skin and liner are either separate parts (I assume they are) and in a different color just to make sure KS recognizes them as separate surfaces. Next, be sure your ray bounces are set higher- try about 12 or so. And while you are setting up, make sure Indirect Lighting (settings tab) is checked. Let us know how you make out- glass is always fun!

Wow, thanks Speedster! After all that time, just those few tweaks made all the difference in the world. My shots look great now! Thanks again for your awesome tips. ;D
Will you post one for comparison?
Glad to help. Now- show us how it looks!

Photo comparo! The blue of the inner plastic is a little brighter in this one, but it doesn't change the fact that it looks 1000x better.
Super! Now, in the Scene Tree- just "lift" or raise your entire model just a tad from the ground to break the white surface on the bottom. Try about 0.005 or so above where it's now set.
