This project has been done for a building in Paris.
It consits to update the building with a new 2 wall glass skin.
It was more difficult than it appears on render becose the second skin go away from the first one with curved shape...
So all pieces have different lenght to match the space beetween the 2 wall of glass, but also, beetwen each column all pieces changes (4 differents in fact) ..and each pieces are composed from a lot of differents pieces too.
Was more long to make than i imagine.
Soft: 3dsmax 2013 + VRAY 2.3 + PS
