Thank you very much for your quick reply.:-)
I think I just found something I dont like on Poser. I agree, its easy in this way but is not practic.. I have to stop my scenic, open a new one, make my "earth ball", export it and then re-open my scenic... except I am doing things in the wrong way.. My last experiences trying to add stuff to library were frustated because everything on scenic went to library, not only the object..
Thank you again.:-)
