Hi,

I'm doing some parts with glass panels, with no background and being dropped onto pure white in photoshop. What is the best environment to use to keep the glass as clear as possible? A white constant dome? Or try changing glass mat. properties to make it as clear as possible. If I turn off the background then the glass is too dark, it inherits it and ends up looking smoked.

Thanks,

If I'm rendering glass or transparent plastic onto white and need an alpha, I tend to set the refraction layer as a pure white .mxi file with quite a high value (50+ if you want to really blow it out).

Doing this allows you to keep a good alpha, keep your scene/HDRI lighting settings and leave your glass material as it is.

Hey cool, I actually tried that and it would have worked great, except I have floor and objects behind the glass, sitting on a shadow catcher, so the refraction layer artificially blew out the shadows behind it.

It's funny, in a program like solidworks I can just set the scene background to pure white, and it's a perfect setup, shadows on the floor around the object and a white background, with zero work. I've tried about 20 crazy techniques to do this in maxwell and just ended up using photoshop!!
