SU Model Mirrored into Bryce, and doubled faces

[dragontech]

I'm using SU 2015 Make. I made a model, exported as dae., then imported into Bryce 7 Pro.
Came out great EXCEPT, it mirrored. The right side is now the left side. LOL I could probably flip the model before exporting out of SU, but does anyone know why it does this?

2nd part is, any way to not get dual faces when exporting? If I want a piece of the model a certain color in Bryce, then I have to delete the top copy of that piece, and then color/texture the 2nd copy. Not a big deal really, unless I'm doing a lot of piece different colors/textures.

Thanks for any input.
