Thanks Hoofdcommissaris.  I forgot to mention that whatever the tool may be it must export the creature in a format I can import into Vue Infinite.  The three 3d formats I've found to work well for me in Vue Infinite for importing objects from other applications are as follows:

.psz3 (Poser)
.dxf
.obj

There are other import formats Vue accepts but I have not tried them like from Lightwave and 3Ds Max.  Vue is the final destination in many of my 3d projects where I import Poser characters, prop objects from vendors, or personally created items in Cinema 4D such as props like furnture, equipment, etc.  If I do use another tool to create creatures then I need to be able to import the output into Vue for the final scene or into Cinema 4D (which takes .obj) where maybe it needs some adjustment.
