Work in progress.
Cycles render.
Trying to place a fake reflection on the glass but its not working right.
The fake reflection works but any thing in front of it does not show up.
I placed trees in front of the glass to reflect but there is no reflection.
There is no reflection of the walls also. It looks like a porthole to another dimension.
Update.
I think that I got an idea.
After this render planning tol remove the top portion
and replace it with a duplicate of the bottom.
Another Update:
