If your characters have no lighting, make sure they are using Vanilla+ Shaders
There is also a bug with Node Constraints and Timeline where when you switch characters, the penis will no longer be attached to the vagina. This is because Timeline has deleted the keyframes related to Node Constraints after switching.
The easiest way to fix this is to open Node Constraints (Ctrl + i), find "cf_j_vagina_root -> k_f_dan_entry" and re-activate it (click on the dot to the left). You will miss out on the first part of the animation where the penis is rubbing against the pussy, but that's it.
However, if you want to retain the full animation, you must create a new keyframe on Timeline. I have recorded a short video on how to do this: https://mega.nz/file/jQEGWKQL#NnBGGz79qBJyAJKaapM4cGIwnlHRt1aCQzI3sKxzntk
