I'm trying to learn some tricks with Koikatsu Studio, but I'm quite obsessed by this image. The author says he made that horsecock using KKPE (which I'm learning right now), but I sincerely don't understand how he did it. From what I can see, he basically flattened the cock tip and created a bulge in the medial part of the cock to simulate the "ring" horses have. But I can't find the bones to do such things.
I can change the bones at the base and at the tip of the cock (they are called something like "cm_J_dan"), but I can't make morphs like this with those.
Could someone please help me here?
