I've used trueSpace some. I believe numeric entry for coordinates and the like are available through right clicking the selection tool. I like both RayDream/Carrara and trueSpace. Both are reasonably intuitive, reasonably priced, and each has its strong points. trueSpace has more tools and available plug-ins, Carrara comes stock with more special effects, both have global illumination (although C2 is first to arrive with caustics), etc. Some objects and scenes seem to align better with Carrara's toolset, some with trueSpace's. Although there are more expensive programs that may offer a bit more, I suspect that most Carrara and trueSpace users are hard pressed just to keep up with those packages continuing progression of new features and capabilities, and that it has gotten to the point where the artist's skills and available time are now pretty much the limiting factors anyway. Enjoy. rj
