UV Mapping problem, please help

[derei]

I downloaded This File from 3DWarehouse and I want to add thickness to petals (using JPP), to be able to render with SSS material in Twilight render, but I can't apply mirrored texture on the extruded side of the petal.
Please guide me how to do it. What plugins do I need to apply mirrored UV on that?

I repeat: as Twilight Render manual specifies, for good results, with SSS, the object must have thickness, so I don't want to mirror the material from front to back, but from the "inside" of the flower, to the "outside".

Thank you for help.

You need to copy the petal off by 1mm then reverse its face... then all is well... there is only one petal so editing is quiet quick...test_hibiscus.skp
