I had similar problem using Poser 4.03 on MacOS 9.2.2. Made group in Hierarchy from spawned props from grouping tool. Created New Figure in Hierarchy. It showed up in New Figures Library. I loaded it and it appeared in selection menues and hierarchy editor but was invisible in scene. Discovered this workaround. Saved group I intended to make figure from as prop group to Poser prop library. Then loaded prop group from library into scene. Then Created New Figure from the newly loaded prop group in Hierarchy editor. Loaded it back into Poser from New Figures library and it was visible!!! Somehow the transit into and back from Poser's prop library blessed it? If anybody has insight into this I would appreciate it.
