Nope, you're not a liar. As I recall, it took around 80 hours of rendering time alone to convert the Poser file into that 3-minute clip, and probably at least that much time to create all of the key frames. It was a lot of work, and the only reason I finished it was that I wanted to prove that I could actually do it.
Until Poser improves so that it can actually use the processing power of a high-end computer, it's just not practical to do it this way. A high-end animation program like Maya would be a better solution but we are talking about dollars and a learning curve to use it.
RE the cornu, it is penetrating her anus in the pictures that show Sabina resting on it. No one knows how a cornu was actually used in practice, but it's pretty likely that it would have evolved into whatever was cheapest and easiest. I'm exploring the idea here that a cornu could be permanently placed in a location that would work for a broad range of body types - short, tall, male or female - and that the victim would be free to use it or not.
I wanted the distance from the tip of the horn to the face of the cross to be just enough so a victim could rest on the tip or take it up the rectum, but not enough to give any kind of secure resting place. Plus I wanted the least amount of interference possible with the victim's ability to raise or lower herself. The bottom line is that I don't think a cornu like the one I show would enable a woman to take it up her vagina. I also didn't want it to be long enough to pierce or tear a victim inside as that would definitely shorten her time on the cross.
So that's what you're seeing here. I don't claim that it's the way it was, just my own interpretation.
