Hi Guys After a bit guidance here on the best approach to handle something. I am making a glass dome roof for my current project. Similar to the image below. Making the glass dome itself is a no brainer. But its the frame work that supports the glass that I need guidance on. have been thinking of several options but unsure as to the best approach.

1. model the frame work from scratch. And have the glass dome and frame work occupy the same space.
2. create a texture bump and transparency to match the frame work and apply it to the glass dome. And then wonder if I will get the depth of the frame work through the glass as it would be in real life.
3. create a second dome with no thickness to it with all the maps and place over the original.
4. or any other way someone else can think of.

What I am after is that if you walked up to the dome you would see that the glass looks like panels sitting in the frame work.
