Attached Link: C5 Native Tut

B you can check out my tut on the cr2 thing to see if it helps. I will say that I have never seen textures or lighting tho that doesn't need adjustment. Often alot. The beauty of native is u can save it in Carrara. And u should be able to use particles and/ or micro displacement to make a waterfall in C5. :tt2:

No need to think outside the box....
    Just make it invisible.
