This thread is resolved. Here is a description of the problem and solution.
Problem: Translating Smart Slider 3 or showing different smart slider3 in secondary language.
Solution: You only need create separate slider for each language. you may be able to duplicate your main language slider for each other language. You can then place your translated strings manually in each language's slider, and use the appropriate slider in your translated pages or posts.
