mapping organic shapes

[Petra]

Hi there,
I have a problem with mapping organic shapes - in this case bended tube (in all directions).
I have exported the model from 3Ds Max to obj and than imported to Keyshot.
When I choose Uvw coordinates mapping it gets strange mapping.
I have attached image of the tubes I would like to map. And the final image I need to achieve. (The light blue tube).
Thanks for any help!
