How to create a glass like appearance using a generic appearance?

Hi John,

Technically you should be able to re-create almost any appearance using a 'generic' appearance. However with very specialized appearance types, such as glass, it's best to use the proper Glass appearance type. That also simplifies the available settings per each appearance type, making it easier to dial in that perfect appearance.

Brian is correct.  Sometimes it's best not to overthink what just works.

That said - using the Generic type is a great way to understand what various settings do.  Some types have settings not exposed in generic, but in any case, a basic transparent glass can be replicated I guess.  See attached which should come pretty close to the shipped "Transparent Glass"...  I didn't do final offline renders to compare but an eye test after some passes in the viewport and they look close.  Should be anyhow.
