I am still using my 3DX pipeline version to move content into iClone 8. The Export option in the File menu allows you to export with IC7 or IC8 as the target. Just pick IC8 from the Target Version drop down and use the Other destination option to choos a path to your IC8 custom content. I've used it for both props and animated characters. I've also used it to convert.BVH animation files into iMotion.
