Procedural Nature Pack - Vol.1

Hi , is it possible to export river from a project to another project ? I also try to convert my river blueprint in to a static mesh but the mesh is broken by the number of the spline segment.
Also, do you gone to do some update on this package . (like beter foliage like you do for your other pack.) It sound wierd to me that you put other pack on the macket place wiht some fix ,that we should have not be implemented in to vol 1.
