Complex Lit translucent glass(plastic) physically correct

[xjapanese]

Hi Guys,

 

Anyone has any idea how to make the material that looks like that :

 

It has to be physically correct as I will have a complex geometry.

I played a lot and can't seem to get it....

I know how to fake it but in my case doesn't help.

 

Thanks!

Isn't that just total internal reflection/refraction. Just a solid piece of perspex/glass/whatever placed over a light, and such is the index of refraction that it creates that effect?

That said, I can't get it to happen with a simple setup. Perhaps it is more complex than I had bargained for.

Realize with blend material acrylic clear and frosted for edges. Focus on visual physicality, light the frost- exclude all else.

Etchings and carvings the same.

Thanks Ismale ! that is what my last hope is ..will use translucency for the frosted I guess to be able to control the scattering some how..

Thanks Chris...That is what I tried but that can work only if you choose the right angles which I can do in my geometry setup as they will be many
