H-animation in progress and "pls have mercy on me, Unity" (Patreon)

Hi everyone! Omega here and i just wants to talk about animations, so i have done some trials because there are various ways to construct animations, i build a test animation which  you can see in pictures: male hugging female from behind, penis goes into vagina, male's hand caressing female's breasts, left hands holding together. It's looks so nice and smoothly.... until unity breaking and turning the rig into tentacle monster (x_x)⌒☆ . So not every poses are possible in unity, not to mention Koikatsu. I did try to fix it but hopeless, so i'm building new rig and change my idea to be more compatible. It's hard to recognize problem because animations could running fine in blender but not the same for unity, after all they are two different environment. I'm feeling confident that i will achieve H-animations no matter how many times unity breaking my rig  ＼(≧▽≦)／
Please be patient with me and thank everyone for supporting, here is another good news that i will make a guide on building H-animation after finishing the project  (*￣▽￣)b
