It has been decided that the movie's explicit sex scenes will be filmed in Hollywood, since the filmmakers are concerned that they should not offend sensibilities by shooting the graphic content in India, the Hindustan Times reports.
The film's director Rupesh Paul said: "I was getting calls from my friends, warning me that no nude scenes should be shot in India. It may create unwanted issues. Some communal organisations can even exploit the situation just to make headlines.
"Considering the touchy cultural atmosphere [in India] and the people's sentiments, we have decided to shoot the scenes outside India. I met a line producer here who is well experienced in the field, and can easily facilitate any studio in Hollywood for the nude scenes."
The rest of the film will be shot on location in Gujarat, Rajasthan, Madhya Pradesh and Mumbai.
Paul says he plans to premiere Kamasutra 3D at the Cannes Film Festival in 2013.
Chopra, who caused controversy by becoming the first Indian woman to pose naked for the cover of Playboy magazine , said she struggled to get acting roles before posing for Playboy.
