Now the semen will directly pass through the character and fall on the ground, which really feels very unnatural. I really hope that there can be some interaction between the semen and the character. I know that implementing fluid physics is very difficult, but can't we think of some other ways? For example, we could just cover the character with a texture, just like the effect when it falls on the ground, or we could freely adjust the mask and texture on the character in the animation, so that users can draw and add their own bukkake textures.
