I did misspeak… I meant to say thatt here is no way to change the effects of illumination on just a single item… that it is all or none…
Thanks a lot to all of you—sorry I didn’t post back any sooner, the week was too turbulent to think straight, and I would’t want to write garbled nonsense.
Thanks mrwmrutski, too—this is good, even though it isn’t actually white (i would think it’s ground glass).
I have indeed dyed the glass in the attached file white through and through, to no avail. Likely I’ll stick with photoshop for the time being, while still interested in including a simulation of actual translucent milk glass (meaning glass as milk: White, not ground, yet translucent).
Thanks again!
