Yes, it should work perfectly while possesing. Maybe you have to go to FOM/ViewScan and select female targets only. It could be that the male face blocks the view. Could you try that? I did not test that extensively, but it would be possible to shift the view trigger forward to have a "blind" range infront of the eyes.Just a thought! It would work if you possess/embody the male person I assume right?
I also gave the person-person thing some thoughts:
I won't detach the scan from the camera rig, because that would break the lighting and DoF features of FOM. I could, however, write a separate plugin to put on person#2, which only adds the ViewScan system. In WatchMe there could be a setting to choose wheter the triggers should react to the player or another person, or both.
BUT: I don't think that this will yield good results. Your head animation of the male had to be VERY precise to make it work. Natively, the view trigger would be parented to the male head. I could make it point to the eye target, but something like Glance won't be suported.
On a second thought: Well, yeah, I could also support Glance by getting the view direction from the eye bones I guess. But is all of this really worth it?
