How do you handle reflections and transparent objects like glass?

Is there any chance to tell the program what level of transparency an object has? Here the marked region should have a wall of glass.

Behind the garbage can there were some bicycles. The tires are recognized in some way, but thin objects like the spokes were never modelled. Did anyone manage to capture a bike? or transparent objects?

Transparent objects cannot be reconstructed until turned to matte and dirty. You have to physically “convert” the object to a structured and patterned one by dusting, making it dirty, spraying… etc
