Pinball playfield lighting
I'm wondering how to achieve the effect of having backlit translucent plastic. I'm specifically working on a pinball playfield, and I'm not sure how to get the extremely vibrant lights on the playfield to look right. I've attached on and off states from a light on a Pinball FX2 playfield as reference.

I had initially tried using a transparent shader on a plane, and simply illuminating the transparent area from underneath, but of course the light doesn't go through the plane, so I tried to fake it by putting another plane underneath so that the light was seen reflecting off of that through the transparency. It kind of works, but it doesn't give me the sharpness and vibrancy that the attached images have.
I also tried faking it by lighting it from above, but of course that doesn't work properly because the black outlines are equally illuminated, which sort of washes it out and ruins the effect.
I thought this would be pretty simple but now I'm stumped. I'm thinking I need a specific shader to get the proper effect, but I just don't know what to try at this point. Any help is greatly appreciated.
Have you tried forgoing lighting and using static images ins$$anonymous$$d? It seems that you might be able to switch out the unlit image for a lit image, and maybe turn on a point light above it if you want it to light up other objects
I did end up swapping out textures and using a point light above to handle a bit of light reflection on nearby objects. If you'd like to leave that as an answer, I'll be happy to mark it as accepted. Thanks!
