first realistic AI quad tests - as promised (5 short gifs)

It was a bigger struggle than I thought, I must say. Turns out (at least for hunyuan ai), training limbless lora is quite a struggle as well. I theorize that similarly to the hemi - it's very hard for it to see the human body and let go of such huge parts to turn it into a limbless amputee. It seems to me EVEN THE POTGIRL concept was easier for it to learn - since it didn't really have to see the body - understands what a pot is. You can notice in these first successful attempts it tends to try to crop out the legless part which is because it's very much not sure about it being right - in one gif the hips are kinda weird shaped too. But I intend to put more work to fight this problem, just as I do with the hemis.
Here is the good news about this though. It seems that armlessness is pretty easy for it to learn, haha. So I'm thinking pretty sure I should also focus on making another armless movie trailer or such, with a new consistent character. OR maybe even a return of our original detective in some new fun situations. Not sure yet.

As for the hemi concept - if it helps, just cutting below the rib cage will do.

2025-04-13 17:58:15 +0000 UTCThe third GIF seemed to be about the best to me. It had a little bit of lower body definition while still lacking the legs. The fourth and fifth seemed to put too much body below the belly button. I suspect the reason for the problem is that arms have a pretty clear transition - the side of the body makes a nice vertical "cut" line for complete removal of arms. Legs, on the other hand, are less well defined. The crotch is much less visible as a defining cut point, and legs are also more of an angle instead of a straight connection. The hemi shape is an even more notable example of the same problem - it is hard to define where the bottom of the torso should be, since it is somewhere below the rib cage, but above the top of the pelvis, which is rarely clearly visible on many healthy people.
